Substance: Ammonium Tartrate Dibasic
Chemical Formula: C4H12N2O6
CAS Number: 3164-29-2
Concentration: 99–100% by weight
Impurities: Trace amounts of water, potentially less than 0.5%; consult manufacturer for possible residual contaminants from synthesis
Inhalation: Move to fresh air. Support breathing as needed. Seek medical attention if coughing or respiratory discomfort persists.
Skin Contact: Remove contaminated clothing. Wash eyes and exposed skin with plenty of water and soap. Seek attention if irritation continues.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing and seek medical advice if discomfort persists.
Ingestion: Rinse mouth with water. Do not induce vomiting unless directed by medical personnel. If large amounts ingested or symptoms appear, seek medical advice.
Most Important Symptoms/Effects: May provoke mild irritation symptoms at points of contact. Generally low toxicity but ingestion of large amounts can cause gastric upset. Prolonged or repeated exposure may intensify symptoms.
Suitable Extinguishing Media: Use dry chemical powder, carbon dioxide, foam, or water spray. Do not use strong water jets.
Unsuitable Extinguishing Media: Avoid using straight water streams that may spread powder.
Hazardous Combustion Products: Heating or fire may release ammonia, nitrogen oxides, and carbon oxides.
Special Protective Equipment for Firefighters: Use self-contained breathing apparatus and full protective gear.
Specific Methods: Cool fire-exposed containers with water spray to prevent pressure build-up.
Explosion/Fire Hazards: No particular risk of explosion but dust may pose a slight risk in confined spaces.
Personal Precautions: Avoid breathing dust and contact with eyes and skin. Use suitable PPE such as gloves, goggles, and a dust mask.
Environmental Precautions: Prevent significant spillage from entering drains or watercourses. Collection should minimize dust generation.
Methods for Cleaning Up: Sweep or vacuum up material and place in a suitable disposal container. Avoid raising dust. Wash spill site after material pickup.
Emergency Procedures: Ventilate affected area. Restrict access to spill zone until cleanup is complete if large quantities involved.
Handling: Avoid creating dust and inhaling particles. Wear appropriate protective equipment, keep containers tightly closed, and work within fume extraction if available. Practice good laboratory hygiene practices, including handwashing after handling.
Storage: Store in a cool, dry, well-ventilated, and locked area. Keep away from sources of heat, ignition, and incompatible substances like oxidizing agents. Segregate away from food and beverages. Ensure containers remain well-sealed when not in use to reduce moisture absorption.
Occupational Exposure Controls: No established OSHA or ACGIH occupational limits for ammonium tartrate dibasic. General dust exposure guideline: set limits according to nuisance dust standards—Total dust 10 mg/m3, Respirable dust 3 mg/m3.
Engineering Controls: Employ local exhaust ventilation or work in fume hood for powder handling. Install eyewash stations and safety showers.
Personal Protective Equipment (PPE): Eye protection with safety goggles; gloves (preferably nitrile or other chemical-resistant types); laboratory or chemical protective clothing; filtering respirators if airborne dust exceeds limits or causes irritation.

Incompatible Materials: Strong acids, strong bases, oxidizing agents
Hazardous Decomposition Products: Ammonia, nitrogen oxides, carbon monoxide, carbon dioxide when decomposed by heat
Acute Toxicity: No specific toxicity data for ammonium tartrate dibasic in humans; related ammonium salts cause mild irritation if ingested in moderate quantities. Estimated low oral toxicity.
Skin Corrosion/Irritation: Not classified as corrosive, but may cause minor, reversible irritation on contact.
Serious Eye Damage/Irritation: Transient irritation is possible after contact.
Respiratory/Skin Sensitization: Not expected to cause allergy or sensitization effects.
Chronic Toxicity: No reports of long-term health effects from routine laboratory or industrial exposure.
Carcinogenicity, Mutagenicity, Reproductive Toxicity: Not listed as a carcinogen or teratogen by ACGIH, IARC, NTP, or OSHA.
Other Data: Ammonium ion can cause metabolic effects if consumed in high doses, especially by persons with liver or kidney disorders.
Ecotoxicity: Ammonium and tartrate ions may contribute to nutrient loading in aquatic environments. High concentrations of ammonium may have toxic effects on aquatic life.
Persistence and Degradability: Readily biodegradable under typical environmental conditions. Tartrate degrades naturally; ammonium converts by microbial action.
Bioaccumulation Potential: Both ammonium and tartrate display low bioaccumulation potential in most ecosystems.
Mobility in Soil: Soluble in water and can leach into groundwater if released in large quantities.
Other Adverse Effects: Prevent run-off to waterways to safeguard aquatic organisms; follow local guidance to prevent excessive environmental exposure.
Waste Disposal Methods: Chemical residues—small quantities—may be diluted with water and disposed in accordance with local, regional, and national regulations. Large amounts should be collected as chemical waste for licensed disposal operators.
Contaminated Packaging: Rinse containers thoroughly before discarding; empty packaging must comply with regional regulations for chemical residues.
Special Precautions: Avoid release to environment, drainage, or surface water. Seek guidance from local authorities or an environmental health and safety officer.
