Chemical Name: L-Kynurenine
Common Synonyms: None widely used in mainstream laboratories
Chemical Formula: C10H12N2O3
Appearance: Pale yellow to white crystalline powder
Odor: Largely odorless in most settings
Recommended Use: Research chemical, used for academic and laboratory purposes, not cleared for food or pharmaceutical use.
Main Hazards: Acute oral or inhalation toxicity has not been widely reported for small volumes, but the effects of accidental ingestion, inhalation, or eye exposure have not been exhaustively studied
Irritation: Powder may irritate eyes, skin, or respiratory tract if mishandled
Environment: Not considered acutely hazardous to the environment, though consistent lab norms treat all chemicals as possible long-term pollutants
Risk Symbols: No international pictograms directly assigned, but cautious approach is routine
Main Ingredient: L-Kynurenine at laboratory grade purity
Known Impurities: Trace moisture, minor synthetic byproducts, usually present in insignificant amounts following purification
Other Ingredients: Laboratories rarely blend this compound; published composition relates to the pure substance
Eye Contact: Flush with running water for at least 15 minutes without rubbing; seek medical check if irritation persists
Skin Contact: Wash skin promptly with soap and plenty of water
Inhalation: Move affected person to fresh air; if symptoms develop, seek medical attention
Ingestion: Rinse mouth, do not induce vomiting, take medical advice based on local protocols; only small quantities typically present during routine research
Suitable Extinguishing Media: Dry chemical, CO2, foam, or water spray (use method most appropriate for surrounding fire)
Special Hazards: Burning may release nitrogen oxides or carbon oxides, standard for organic compounds
Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective clothing
Personal Protection: Use protective eyewear, gloves, and dust mask to avoid direct contact or inhalation
Spill Response: Gather spilled powder gently with dampened paper towels; avoid raising dust; dispose of according to chemical waste norms
Containment: Prevent access to drains or water supplies by covering or blocking drains temporarily
Handling: Work in a chemical hood if possible; use gloves and avoid unnecessary skin contact
Storage Requirements: Store tightly sealed in a cool, dry cabinet, away from strong acids, bases, or oxidizers
Avoid: Exposure to heat, direct sunlight, moisture; handling in spaces without proper ventilation
Eye Protection: Wear safety goggles or a face shield
Skin Protection: Standard lab gloves and closed shoes; check gloves regularly for degradation or holes
Respiratory Protection: Dust mask or N95 respirator if powder will be present in air
Engineering Controls: Fume hood use for weighing and transferring powder; use of local exhaust preferred
Exposure Limits: No established occupational exposure limits, so minimize direct contact and airborne particles whenever possible
Physical State: Solid
Color: Pale yellow to white, depending on purity
Melting Point: About 250-252 °C (reported in research literature)
Solubility: Water soluble
Odor: Odorless
Boiling Point: Not available due to decomposition before boiling
Chemical Stability: Stable under ambient laboratory conditions
Incompatible Materials: Strong oxidizers, acids, bases may degrade the compound
Hazardous Decomposition Products: Possible carbon monoxide, carbon dioxide, and nitrogen oxides if burned or strongly heated
Polymerization: No evidence of hazardous polymerization under normal storage or use
Routes of Exposure: Eye, skin, inhalation, ingestion
Potential Effects: Short-term irritation at high levels or with long exposure; not widely reported as highly toxic
Carcinogenicity: No strong evidence or regulatory labeling that links it to cancer
Medical Conditions Aggravated: Pre-existing allergies or respiratory conditions could be worsened by exposure to powders
Mobility: Soluble in water, so spills can spread in aqueous systems
Persistence and Degradability: May degrade by natural processes, not known for extreme persistence
Bioaccumulation: No reliable data, although current research gives little indication that it bioaccumulates
Aquatic Toxicity: Lack of evidence for acute toxicity, but spills in sensitive environments should be prevented out of caution
Waste Treatment: Submit all waste material to a certified hazardous waste disposal operator
Container Disposal: Triple rinse empty containers, then segregate for pickup by chemical waste management teams
Sewage Disposal: Never wash into drains or sewers, compliant with best lab disposal rules
Shipping Name: L-Kynurenine for laboratory use
Transport Hazards: Not listed as a dangerous good for routine air, road, or rail transport under standard lab quantities
Packaging Requirements: Secure packaging to prevent spills, clear labeling as laboratory specimen
Labeling: Follow hazardous material labeling if required by university, state, or federal guidelines
Regulation: No international restriction for research use; not approved for food, clinical, or agricultural application
Worker Safety: Observe OSHA, NIOSH, or EC recommendations for good laboratory practice in handling, storage, and disposal
