Chemical name: 5-Mercapto-1H-Tetrazole-1-Acetic Acid.
Chemical formula: C3H4N4O2S.
Appearance: Usually a white to off-white crystalline powder.
Odor: Slight or no detectable odor.
Uses: Commonly found in research labs, rare in commercial products.
Solubility: Moderately soluble in water.
Molecular weight: About 176 g/mol.
Main risks: Harmful if swallowed, inhaled, or absorbed through the skin.
Symptoms: Exposure might cause irritation of eyes, skin, and respiratory tract.
Environmental risk: Potentially toxic to aquatic life with possible long-term impacts.
Physical hazards: Not especially flammable, but decomposes under strong heat.
Chronic risks: Long-term effects not well-studied, which asks for a strict application of caution.
Main ingredient: 5-Mercapto-1H-Tetrazole-1-Acetic Acid, high purity in most laboratory samples.
Contaminants or by-products: Unreacted starting materials from synthesis sometimes present at low concentrations.
Eye contact: Flush eyes with water, keep eyelids apart, rinse for ten to fifteen minutes.
Skin contact: Remove contaminated clothing, wash skin with generous amounts of soap and water.
Inhalation: Move to fresh air quickly, support breathing if needed.
Ingestion: Rinse mouth, never give anything by mouth to an unconscious person, and seek medical attention.
Advice to physician: Treat symptomatically, monitor for allergic reactions.
Suitable extinguishing media: Dry chemical, carbon dioxide, or foam recommended.
Specific dangers: Thick, irritating fumes can form if compound burns.
Protective equipment: Standard firefighting gear plus self-contained breathing apparatus.
Combustion products: Nitrogen oxides, sulfur oxides, and possibly highly toxic gases.
Spill cleanup: Use personal protective equipment, collect up solid using non-combustible absorbents.
Containment: Prevent leaks from entering waterways or sewers.
Ventilation: Operate in a well-ventilated area or fume hood.
Decontamination: Clean affected area with water and detergent.
Storage temperature: Store in a cool, dry, and well-ventilated area away from heat and strong oxidizers.
Container: Keep tightly sealed, labeled properly, and out of incompatible material proximity.
Handling practices: Minimize dust generation, avoid breathing vapors or dust, wash hands observing strict hygiene after handling.
Segregation: Store away from food, beverages, and incompatible chemicals.
Engineering controls: Use fume hoods or local exhaust ventilation.
Personal protection: Wear laboratory coat, gloves (nitrile or neoprene), and protective eyewear.
Respiratory protection: Use NIOSH-approved respirators in dusty environments.
Hygiene: Wash hands thoroughly after handling; remove contaminated clothing before eating.
Form: Crystalline powder.
Color: White or off-white.
Melting point: Decomposes before melting at high temperatures.
Solubility: Modestly soluble in water, greater solubility in some polar organic solvents.
pH: Acidic in aqueous solution.
Odor: Not strong, often described as lacking scent.
Stability: Recommended storage at room temperature in a sealed container retains the substance’s stability.
Reactivity: Avoid mixing with strong oxidizing agents or strong acids.
Decomposition: Heating or burning can lead to formation of toxic gases like nitrogen or sulfur oxides.
Polymerization: Not known to polymerize under normal conditions.
Acute effects: Can cause skin and eye irritation, respiratory discomfort, and digestive upset if swallowed.
Chronic exposure: Information limited; exercising extra caution makes sense.
Routes of entry: Inhalation, ingestion, skin contact, eye contact.
Symptoms: Might include sore throat, coughing, redness, nausea.
Aquatic toxicity: Likely hazardous to aquatic life; prevention of environmental discharges essential.
Persistence: No solid data on degradation or persistence in soil and water.
Bioaccumulation: Not defined, so avoiding release into nature stays a priority.
Methods: Treat waste as hazardous: incinerate in a licensed facility or contact an approved chemical waste disposal company.
Permanent disposal: Avoid disposal in landfill or drains to prevent water and soil contamination.
Container cleaning: Triple-rinse and follow regional hazardous waste protocols.
Hazard class: Not widely classified, but precautions mirroring similar laboratory chemicals apply.
Packing group: Take the most restrictive approach for confined transport.
Precautions: Label packages clearly, avoid vibration and impact, carry paperwork describing inherent risks.
Government control: Regulations in some countries address handling and disposal.
Workplace requirements: Adhere to local and federal safety and health regulations.
Environmental standards: Stay updated on local laws about aquatic and land impact, since rules can change on short notice.
