Substance Name: L-Alanyl-L-Glutamine
Chemical Formula: C8H15N3O4
Synonyms: Alanylglutamine, AGN
CAS Number: 39537-23-0
Physical State: White to off-white powder
Common Uses: Nutritional supplement in cell culture, pharmaceutical preparations, sports nutrition
Exploring new compounds in the lab begins with clear, trustworthy identification. For L-Alanyl-L-Glutamine, researchers recognize it by a straightforward formula, simple color, and its increasingly important role in nutrient-ready cell environments. Awareness of its synonyms removes confusion, letting everyone in the lab share a common language when safety is at stake.
Classification: Generally recognized as low hazard, non-flammable
Potential Health Effects: Inhalation or direct skin contact can trigger mild irritation, especially for people prone to allergies
Label Statements: Handle with care to avoid dust, avoid contact with eyes and prolonged skin contact
Maintaining awareness around any commonly used compound in research spaces matters, even for low-risk ingredients like this one. Dust inhalation might seem trivial but, from experience, respiratory discomfort builds over time, and there’s no value in cutting corners on personal wellbeing.
Chemical Composition: L-Alanyl-L-Glutamine is a single, well-defined dipeptide
Purity: Typically exceeds 98% for research-grade material
Keeping pure chemicals on hand gives reliable results. This single-ingredient dipeptide means most people in the lab can focus on their work without fear of hidden contaminants, but regular verification remains a solid practice. Subtle impurities in chemicals have derailed many hours of research for the unwary.
Inhalation: Move to fresh air, seek medical attention if breathing difficulty persists
Skin Contact: Rinse skin with plenty of water and soap, remove contaminated clothing
Eye Contact: Rinse eyes gently with water for at least fifteen minutes
Ingestion: Rinse mouth and drink water, seek help for large doses or persistent symptoms
Simple steps build core safety routines, so nobody needs to make a tough call in the moment. Inexperience, haste, and distractions all increase risk. Having a routine, well-practiced response with steps everyone remembers—this is more valuable than the fanciest first-aid box.
Suitable Extinguishing Media: Water, foam, carbon dioxide, dry powder
Unusual Hazards: None reported; does not fuel fires
Protective Equipment: Use standard protective gear for small chemical fires
In an emergency, panic spreads much more quickly than a fire ever does. Training and signage work best when people know what’s actually flammable and what isn’t. For L-Alanyl-L-Glutamine, the lack of special fire concern lets the team focus on saving lives and equipment without worrying about unpredictable flare-ups.
Personal Precautions: Prevent dust generation, ventilate area
Cleanup Methods: Scoop up spilled powder carefully, dispose of in sealed containers
Environmental Procedures: Avoid washing large quantities into drains or waterways
Every spill, no matter how small, reminds us that most lab mishaps come from small moments—a jostled beaker, a dropped scoop. Having the right cleanup tools nearby and not relying on makeshift fixes lowers risk. Multiple teams working together share the responsibility for a clean work environment.
Handling Practices: Minimize dust, wear gloves, avoid direct contact
Storage Conditions: Keep containers tightly closed, store in a dry and cool place
Regardless of how familiar a material feels, routine drops off without attention. Storing powders where moisture won’t sneak in prevents clumping and spoilage—simple, practical measures that safeguard quality and health. A messy bench and open containers never helped anybody.
Airborne Limits: No specific occupational exposure limits established
Ventilation: Use standard lab ventilation or local fume extraction
Personal Protection: Gloves, lab coats, eye protection as common sense dictates
Staying healthy in the lab doesn’t take high-tech gear. It’s about building reliable habits—gloves go on, goggles go over the eyes, coworkers remind each other not to get careless. Trust grows when everyone follows the same rules, and trust protects health better than rules written on a wall.
Appearance: White to off-white, free-flowing crystalline powder
Solubility: Readily soluble in water
Melting Point: Decomposes above 200°C
Odor: Odorless
Compounds like L-Alanyl-L-Glutamine thrive in standard lab environments, standing up to average conditions without fuss. Its stability means that carefully planned experiments aren’t derailed by subtle environmental shifts. Everyone in the lab works better with reliable, predictable materials.
Stability: Stable under normal handling conditions
Reactivity: No dangerous reactions expected with air, water, or common chemicals
Workflows in the lab stay productive when materials don’t introduce surprise complications. Reactivity can become a headache only if ignored, so hands-on checks and updated materials lists keep the bench clear of unplanned chemical drama.
Potential Effects: Low acute toxicity, not known to cause long-term harm in standard lab settings
Possible Irritation: Skin and respiratory irritation possible with sustained or repeated contact
Research keeps showing that chemicals considered safe deserve respect—especially for people with allergies or other sensitivities. Looking after your coworkers by advocating sensible controls even for “easy” compounds reflects care for the whole team.
Ecotoxicity: Not expected to pose a significant hazard to aquatic or terrestrial life
Biodegradability: Readily broken down in the environment
Laboratories carry responsibility far outside their doors. Reducing chemical loads dumped down drains supports healthier communities and waterways. It’s easy to assume “safe” compounds mean zero impact, but lasting lab cultures treat every disposal as part of broader stewardship.
Recommended Disposal: Collect unused or waste material for disposal by licensed chemical waste vendors, following local regulations
Proper lab operation builds on a foundation of good disposal practices. Even compounds with low hazard profiles belong in professionally managed waste streams, not sink drains or general trash. Turning sound disposal into routine avoids headaches if regulators or neighbors pose tough questions.
UN Number: Not classified as hazardous for transport
Transport Precautions: Keep containers sealed and dry, prevent accidental spillage
Shipping compounds between labs introduces a new layer of risk. Extra care with packaging and paperwork simplifies the receiving team’s job and shows respect for everyone’s time and wellbeing. Trust comes from transparency and consistent handling, not from assuming nothing will go wrong.
GHS Classification: Not classified as hazardous under most current standards
Regulatory Limits: No specific restrictions classified for research, but follow all applicable local and institutional guidelines
Regulations don’t always keep pace with best practice. Staying ahead of the rules with careful labeling and shared information protects teams and reputations. If one researcher slips, the whole project—sometimes the whole department—pays the price. Holding high personal standards outpaces reactive compliance every time.
