Dipotassium;bis(antimony(3+));bis((2R,3R)-2,3-dioxidobutanedioate);trihydrate

Dipotassium;bis(antimony(3+));bis((2R,3R)-2,3-dioxidobutanedioate);trihydrate is an antimony-containing chemical compound with the molecular formula C8H10K2O15Sb2 and CAS number 28300-74-5. This complex inorganic salt features antimony in its +3 oxidation state coordinated with tartrate-derived ligands and potassium cations. The compound exists as a trihydrate, meaning it contains three water molecules per formula unit. With a molecular weight of 667.87 g/mol, it is classified as acutely toxic and environmentally hazardous.

This antimony compound is a crystalline solid at room temperature with a molecular weight of 667.87 g/mol. As a trihydrate salt containing potassium and organic tartrate components, it is likely water-soluble and hygroscopic. The presence of antimony typically imparts a white to off-white appearance to such compounds. Being an inorganic salt, it is essentially odorless. The compound's complex structure with multiple coordination sites makes it stable under normal conditions but sensitive to dehydration when heated.

This antimony compound is primarily used as a chemical intermediate and catalyst in specialized industrial applications. Its antimony content makes it valuable in flame retardant formulations and as a catalyst in polymerization reactions. The compound may also serve as a precursor for other antimony-based materials in the electronics and ceramics industries. Additionally, it can be used in analytical chemistry applications and research purposes where specific antimony coordination complexes are required for synthetic or catalytic processes.

Safe handling requires appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing due to its Acute Tox. 4 classification. Work in well-ventilated areas or under fume extraction to prevent inhalation exposure. Avoid direct skin and eye contact, and prevent ingestion. Use proper handling techniques to minimize dust generation. Emergency eyewash stations and safety showers should be accessible. Follow good industrial hygiene practices, including thorough handwashing after handling and before eating or drinking.

Store this compound in a cool, dry, well-ventilated area away from incompatible materials and ignition sources. Keep containers tightly sealed to prevent moisture absorption and contamination. As a trihydrate, protect from excessive heat which could cause dehydration. Store away from acids, strong oxidizers, and reducing agents. Maintain storage temperatures below 25°C when possible. Ensure storage areas are equipped with appropriate spill cleanup materials and that containers are properly labeled according to GHS requirements including Warning signal word and appropriate pictograms.

Immediate action depends on the exposure route. For skin contact, remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. In case of eye contact, flush immediately with water for at least 15 minutes while holding eyelids open. If inhaled, move person to fresh air and monitor breathing. If ingested, do not induce vomiting; rinse mouth with water if conscious. Seek immediate medical attention for all exposure routes, providing safety data sheet information to medical personnel. Remove contaminated clothing before reuse.

Disposal must comply with local, national, and EU waste regulations as this compound contains antimony, a regulated heavy metal. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Do not discharge to sewers, waterways, or soil due to its Aquatic Chronic 2 classification. Small quantities may require neutralization or stabilization before disposal. Contaminated packaging should also be treated as hazardous waste. Maintain disposal records and ensure waste classification codes are correctly assigned according to the European Waste Catalogue.

This compound is classified under ADR Class 6.1 (Toxic substances), Packing Group III, indicating moderate toxicity requiring specific transport regulations. Use appropriate packaging meeting UN specification requirements for Class 6.1 materials. Vehicles must carry proper documentation including transport documents and emergency response information. Drivers require ADR training for dangerous goods transport. Packages must display correct hazard labels and markings. Segregation requirements must be observed to prevent incompatible materials from being transported together. Emergency equipment specific to toxic substances should be available during transport.

This compound falls under multiple EU regulations including CLP Regulation for classification and labeling, requiring Warning signal word and specific GHS pictograms (GHS07, GHS09). REACH regulation applies for registration, evaluation, and authorization, though it is not currently listed as a SVHC. As an antimony-containing substance, it may be subject to restrictions under REACH Annex XVII. RoHS and other environmental regulations may apply depending on end-use applications. Transport is regulated under ADR for dangerous goods, and disposal requires compliance with waste framework directives.
