Chemical Name: Pyrotartaric Acid CAS Number: 505-49-7 Purity: Typically above 98% Impurities: Minor organic acids or residual solvents may be present in trace amounts Other Ingredients: None typically added Molecular Formula: C6H10O4 Molecular Weight: 146.14 g/mol
Eye Contact: Immediately flush with plenty of water for at least 15 minutes, lift eyelids occasionally to ensure thorough rinsing, seek medical attention if irritation persists Skin Contact: Remove contaminated clothing, wash affected area with soap and water, do not use solvents, consult a healthcare professional if redness or discomfort continues Inhalation: Move person to fresh air, provide artificial respiration if breathing has stopped, seek medical attention if cough, shortness of breath, or irritation develops Ingestion: Rinse mouth with water, do not induce vomiting, consult a physician or poison control center, give water if person is conscious Important Symptoms: Irritation, redness, coughing, shortness of breath, stomach upset
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, water spray Specific Hazards Arising from Chemical: May release carbon monoxide and carbon dioxide under combustion, use personal protective equipment Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective gear, avoid inhaling combustion products Special Procedures: Contain runoff to prevent entry into waterways, remove containers from fire area if it is safe, cool exposed containers with water spray
Personal Precautions: Wear gloves, approved mask, eye protection, avoid generating dust, ventilate area adequately Environmental Precautions: Prevent spillage from entering drains, sewers, or water courses Methods for Containment: Scoop up solid material carefully using non-sparking tools, place in suitable container for disposal Cleaning Methods: Wipe small quantities with damp cloth, wash area with water after initial cleanup, ventilate area Disposal of Collected Material: Collect residue for proper disposal, following all applicable local regulations
Precautions for Safe Handling: Avoid breathing dust, wear personal protective equipment, wash hands after handling, keep away from incompatible substances like strong bases or oxidizers Safe Storage Conditions: Store in a tightly closed container, in a cool, dry, well-ventilated area, segregate from food and beverages Special Handling Notes: Use tools and containers designed for corrosive organic acids, keep container labeled clearly Incompatible Materials: Reactive metals, oxidizing agents, strong bases Temperature Sensitivity: Protect from sources of heat or direct sunlight
Exposure Limits: No occupational exposure limits established specifically for pyrotartaric acid Engineering Controls: Use chemical fume hood or local exhaust, ensure eye wash and safety shower stations where material is handled Personal Protective Equipment: Safety goggles, gloves (nitrile or neoprene), lab coat or chemical-resistant apron, dust mask or respirator if dust generates Hygiene Measures: Do not eat, drink, or smoke while handling; wash hands and face thoroughly after handling
Appearance: White to off-white crystalline solid Odor: Odorless Melting Point: 98-102 °C Boiling Point: Decomposes before boiling Solubility: Soluble in water, alcohols, and some organic solvents pH: Acidic in aqueous solution Vapor Pressure: Negligible at room temperature Density: 1.35–1.40 g/cm³ Flammability: Not classified as highly flammable, but dust may form explosive mixture with air under specific conditions Other Properties: Stable under recommended handling and storage, non-volatile
Chemical Stability: Stable under standard conditions, decomposes at elevated temperatures Conditions to Avoid: Heat sources, open flame, moisture, incompatible chemicals Incompatible Materials: Strong oxidizers, strong alkalis, reducing agents Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, possible low molecular weight hydrocarbons Reactivity: May react with strong bases to liberate heat and gases Polymerization: No hazardous polymerization expected
Routes of Exposure: Inhalation, ingestion, skin, and eye contact Acute Effects: Irritation of skin, eyes, and upper respiratory tract; possible nausea and stomach upset Chronic Effects: Frequent or prolonged exposure may lead to dermatitis or respiratory irritation Toxicity Data: Not thoroughly studied; structurally similar dicarboxylic acids have low acute toxicity Carcinogenicity: Not listed by IARC, NTP, or OSHA as a carcinogen Other Possible Effects: No current evidence for reproductive or developmental toxicity
Ecotoxicity: Not classified as environmentally hazardous under typical lab quantities, but large releases to waterways may lower aquatic pH and disrupt ecosystems Persistence and Degradability: Readily biodegradable in soil and water, breaks down by microbial action Bioaccumulative Potential: Not likely to bioaccumulate due to water solubility Mobility in Soil: High solubility leads to dispersal in water, may leach into groundwater Other Adverse Effects: Avoid uncontrolled release; large spills could damage aquatic habitats by acidifying water
Waste Disposal Methods: Follow local, regional, and national regulations for organic acid disposal, use licensed chemical waste contractor Container Disposal: Empty containers may retain residue; triple-rinse with water before disposal, deface labels Environmental Precautions: Do not allow entry into drains, soil, or natural waterways Additional Notes: Suitable for incineration at approved facilities, consult safety officer before large-scale disposal
UN Number: Not regulated as a hazardous material for ground, air, or sea transport in most jurisdictions Transport Hazard Class: Not assigned Packing Group: Not assigned Special Precautions for User: Package securely to prevent release during shipment, clear labeling Transport in Bulk: Verify conditions on bulk transport with carrier, avoid contact with incompatible loads Environmental Hazards: Not considered hazardous for transportation; avoid container damage or spillage
Inventory Status: Listed on TSCA, REACH, Canada DSL, AICS, and other major chemical inventories Labeling Requirements: Standard GHS labeling (hazard pictogram, signal word, hazard/personal protection statements) Other Regulations: Subject to workplace hazard communication standards and clean air/water restrictions in some regions SARA/Title III: Not subject to Section 313 reporting requirements Restrictions: Not regulated under hazardous substances acts in most countries for limited laboratory use Workplace Controls: Employers must provide safety data, hazard training, and proper PPE
