Gabapentin Material Safety Data Sheet (MSDS)

Identification

Product Name: Gabapentin
Chemical Name: 1-(aminomethyl)cyclohexaneacetic acid
Synonyms: Neurontin, Gabarone
CAS Number: 60142-96-3
Recommended Use: Pharmaceutical active ingredient, anticonvulsant, nerve pain relief
Manufacturer Information: Refer to supplier or label for details

Hazard Identification

Classification: Not considered hazardous under typical conditions of use
GHS Label Elements: No symbol mandated, not classified for acute toxicity or environmental hazard
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Potential Health Effects: May cause mild irritation of eyes, skin or respiratory tract with repeated contact; ingestion of large amounts can lead to drowsiness, confusion, or unsteady movements
Precautionary Statement: Avoid inhaling powder or dust, limit unnecessary contact

Composition / Information on Ingredients

Chemical Name: Gabapentin
CAS Number: 60142-96-3
Concentration: >98% pure, typical pharmaceutical formulation may include excipients and binders as inactive ingredients

First Aid Measures

Inhalation: Move to fresh air, provide oxygen support if breathing is difficult, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash affected area with soap and water, seek medical advice if irritation develops
Eye Contact: Flush eyes with plenty of water for at least 15 minutes, remove contact lenses if present and easy to do, seek medical attention for persistent discomfort
Ingestion: Rinse mouth with water, never give anything by mouth to an unconscious person, seek medical attention if feeling unwell, do not induce vomiting unless directed by medical personnel

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical powder, carbon dioxide, alcohol-resistant foam, or water spray for small fires, water may be used to cool nearby containers
Specific Hazards: Combustion may produce toxic fumes of nitrogen oxides and carbon oxides
Protective Equipment: Self-contained breathing apparatus and full protective clothing
Firefighting Advice: Move containers from fire area if it can be done safely, prevent firefighting runoff from entering water systems

Accidental Release Measures

Personal Precautions: Wear protective clothing, gloves, safety glasses, dust mask or respirator if ventilation is inadequate
Environmental Precautions: Avoid discharge to sewers and drains, contain and collect spillage
Methods for Cleanup: Scoop up solid or powder material without generating dust, clean area with damp cloth, dispose of collected material in accordance with local regulations

Handling and Storage

Safe Handling: Minimize dust generation, keep containers tightly closed, use in well-ventilated area, practice good hygiene and avoid unnecessary contact
Storage Conditions: Store in original container, keep in cool, dry area away from incompatible materials such as oxidizers, protect from moisture and light
Specific End Uses: Pharmaceutical production, laboratory research, not for unauthorized use or distribution

Exposure Controls and Personal Protection

Engineering Controls: Use local exhaust ventilation, isolate work area during large-scale manufacturing
Personal Protective Equipment: Wear gloves (nitrile recommended), lab coat, safety glasses with side shields, respiratory protection if ventilation is inadequate
Exposure Limits: No occupational exposure limit established for gabapentin; minimize airborne dust

Physical and Chemical Properties

Appearance: White to off-white crystalline powder
Odor: Odorless
Melting Point: 162–166°C
Boiling Point: Not applicable (decomposes)
Solubility: Soluble in water, slightly soluble in methanol, insoluble in most organic solvents
pH (1% Solution): Approximately 6.5–7.5
Vapor Pressure: Not volatile
Density: 1.2–1.3 g/cm³
Partition Coefficient (Log Pow): -1.1 to -1.3

Stability and Reactivity

Chemical Stability: Stable under normal conditions, sensitive to moisture and light
Conditions to Avoid: Excess moisture, high temperatures, strong light
Incompatible Materials: Strong oxidizing agents
Hazardous Decomposition Products: Emits toxic fumes under fire conditions including carbon monoxide, carbon dioxide, and nitrogen oxides
Polymerization: Will not undergo hazardous polymerization

Toxicological Information

Acute Toxicity: Oral LD50 (rat) >8,000 mg/kg; low acute toxicity
POTENTIAL HEALTH EFFECTS: No evidence of mutagenicity or carcinogenicity from animal studies, some reports of mild drowsiness, dizziness, or coordination issues in humans with overexposure
Skin and Eye Contact: May cause mild, temporary irritation
Chronic Effects: Long-term occupational exposure data limited; medical monitoring may help for production workers
Target Organs: Central nervous system

Ecological Information

Ecotoxicity: Limited data, low bioconcentration potential, not expected to bioaccumulate
Persistence and Degradability: Partial biodegradation in the environment, not persistent under most conditions
Mobility in Soil: Readily soluble, may leach to groundwater with improper disposal
Other Adverse Effects: No significant impact expected at pharmaceutical use levels, risk of aquatic toxicity with large accidental releases remains low but possible

Disposal Considerations

Waste Disposal Methods: Treat as pharmaceutical waste, incineration or disposal through licensed chemical disposal contractor, avoid flushing into sewers or watercourses
