Chemical Name: N-Succinyl-Ala-Ala-Pro-Phe-p-Nitroanilide
Common Use: Research labs often employ this compound as a chromogenic substrate in protease assays.
Form: With its yellow crystalline form, the compound typically arrives as a solid that dissolves in water or certain organic solvents.
Main Hazards: The structure includes a p-nitroanilide group, a functional group known for potential harm if misused or inhaled.
Routes of Exposure: Inhalation, ingestion, and direct skin or eye contact stand out as primary means of harm.
Health Risks: Eye, skin, and respiratory irritation rank high on the list of reported problems with handling similar organic substrates.
Active Ingredient: N-Succinyl-Ala-Ala-Pro-Phe-p-Nitroanilide is a peptide-based compound with a nitroanilide group at one end.
Impurities: Purity varies across suppliers, but trace solvents or by-products from peptide synthesis occasionally remain.
Inhalation: Leave the exposed area right away and inhale fresh air.
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water.
Eye Contact: Rinse opened eye with plenty of clean water for several minutes.
Ingestion: Rinse mouth with water, avoid inducing vomiting, and seek medical advice if feeling unwell.
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical powder, or foam.
Combustion Hazards: Burning this compound can release toxic nitrogen oxides and carbon monoxide.
Firefighter Protection: Proper gear includes self-contained breathing apparatus and full protective clothing under fire conditions.
Containment: Wearing gloves and protective goggles, gently sweep up the powder, avoiding dust.
Cleaning Method: Tools and affected surfaces should be thoroughly wiped and rinsed.
Disposal: Collect in a suitable container for chemical waste and ventilate the spill area.
Handling: Use gloves, safety glasses, and lab coats every time. Good ventilation helps reduce risks.
Storage: Store tightly sealed, away from incompatible chemicals, in a cool and dry spot, since moisture and light could degrade the compound or create hazards.
Engineering Controls: Fume hoods and exhaust fans limit airborne particulates.
Personal Protective Equipment: Gloves, safety goggles, and lab coats become non-negotiable on a lab bench. Respiratory protection may be considered if dust forms.
Hygiene: No food, drink, or smoking in handling areas and frequent handwashing practice is a must for anyone regularly using this reagent.
Appearance: Pale yellow to yellow crystalline powder.
Solubility: Usually soluble in water, methanol, and other organics.
Odor: Odorless, which can lull users into underestimating risks.
Melting Point: Existing studies mention thermal decomposition rather than a precise melting point, so heating this compound is not routine.
Chemical Stability: Stable at room temperature if kept away from moisture and sunlight.
Reactive Scenarios: Strong acids or bases, triggers for decomposition, are best avoided around any nitro-anilide containing compound.
Decomposition: Breakdown during combustion creates a mix of hazardous gases.
Acutely Toxic: Specific published LD50 data is limited, but chemical relatives suggest toxic risks with overexposure.
Irritation: Extended exposure leads to redness and irritation in lab settings; gloves and goggles always seem justified.
Chronic Exposure: Exposure data for lab workers remains rare, yet repeated unprotected use of aromatic nitro compounds is rarely recommended by most occupational health experts.
Aquatic Toxicity: Data is limited, but the nitro group can persist in surface waters, raising concern over bioaccumulation or slow degradation.
Environmental Release: Careful handling helps keep this synthetic peptide off the ground and out of the water, as wastewater plants may not remove complex organics.
Waste Handling: Collect in a chemically resistant, sealable container. Engage local authorities or hazardous waste vendors to keep peptides and nitroanilides out of municipal trash or drains.
Unused Product: Laboratories often hold unused compound for proper bulk disposal during routine chemical cleanup drives.
Shipping: No broad special transport restrictions in most regions, though local regulations may require leak-proof packaging and a written manifest for laboratory chemicals.
Handling During Transit: Protect containers from crushing and temperature extremes that might cause degradation.
Global Regulations: Not listed as a controlled substance in most chemical inventories, but general guidelines for safe handling of potentially noxious or environmentally persistent lab reagents apply.
Lab Policy: University and industrial lab rules often exceed minimum legal requirements, covering hazard communication and routine personal safety training.
