N-acetyl-L-aspartic Acid CAS 997-55-7

1. N-Acetyl-L-aspartic acid is primarily used as a reactant in organic synthesis to prepare compounds such as protected homoserine γ-lactones and racemic amino-substituted succinimide derivatives .
2. N-acetyl-L-aspartic acid CAS 997-55-7 is an endogenous metabolite and a derivative of aspartic acid, playing a significant role in brain metabolism and acting as an acetyl donor in the formation of acetylcholine in the brain .
3. N-Acetyl-L-aspartic acid is employed in biomedical research as a key biomarker for studying neurodegenerative diseases, particularly Canavan disease, and for investigating neuronal health and function .
4. Researchers utilize N-acetyl-L-aspartic acid CAS 997-55-7 in peptide synthesis applications and as a reference standard for metabolomics studies, including tandem mass spectrometry analysis through databases such as the METLIN Metabolite Database .

1. N-Acetyl-L-aspartic acid must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and moisture, with recommended storage at 2-8°C for short-term or -20°C for long-term stability up to 3 years .
2. N-acetyl-L-aspartic acid CAS 997-55-7 is classified with GHS hazard statements H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation), requiring appropriate handling precautions and warning signal .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, avoiding formation of dust and aerosols, and ensuring adequate ventilation in work areas .
4. Keep away from incompatible materials such as strong acids/alkalis and strong oxidizing/reducing agents, and for solution storage, prepare aliquots in tightly sealed vials and use within one month, avoiding repeated freeze-thaw cycles .

1. Isolate the spill area, ensure adequate ventilation, and avoid dust formation when N-Acetyl-L-aspartic acid is released, wearing full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable respirator if necessary .
2. Collect N-acetyl-L-aspartic acid CAS 997-55-7 by sweeping or vacuuming without creating dust, using non-sparking tools, or absorb solutions with finely-powdered liquid-binding material (diatomite, universal binders), and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure, decontaminate surfaces and equipment by scrubbing with alcohol, and prevent the product from entering drains or water courses due to potential environmental hazards .
4. Dispose of collected material according to local, state, and federal environmental regulations, as the substance requires proper waste management through licensed chemical destruction or controlled incineration .

1. N-Acetyl-L-aspartic acid is not classified as highly flammable but may decompose under fire conditions, with a flash point of approximately 211°C and boiling point of 425.3°C at 760 mmHg, emitting toxic fumes when involved in a fire .
2. Use N-acetyl-L-aspartic acid CAS 997-55-7 dry chemical powder, carbon dioxide, alcohol-resistant foam, or water spray to extinguish fires involving the product, selecting appropriate extinguishing media based on surrounding environment .
3. Firefighters should wear self-contained breathing apparatus and full protective gear when handling burning N-Acetyl-L-aspartic acid due to hazardous decomposition gases including carbon monoxide, carbon dioxide, and toxic fumes generated by thermal decomposition .
4. During combustion, may emit irritant fumes; move containers from the fire area if safe to do so, cool exposed containers with water spray, and contain fire runoff to prevent environmental contamination .
