1,1,3-Trichloroacetone, identified by CAS number 921-03-9, is an important organic chemical intermediate with a unique set of physical and chemical properties that dictate its handling and applications. As a colorless liquid, understanding these properties is crucial for chemical engineers, laboratory technicians, and procurement specialists involved in its use and supply chain management.

Physically, 1,1,3-Trichloroacetone has a molecular weight of 161.414 g/mol. Its melting point typically falls between 9-11°C, meaning it can exist as a solid or liquid near room temperature depending on local conditions. Its boiling point is reported to be around 88-90°C at 76 mm Hg, and its flash point is approximately 79°C. The density of 1.512 g/mL at 20°C indicates it is significantly denser than water. Its refractive index (n20/D) is 1.491, a value often used for purity checks.

Chemically, the presence of three chlorine atoms imparts significant reactivity. It is commonly used as a raw material in the synthesis of folic acid (vitamin Bc), an application that requires high purity. Its utility extends to other organic synthesis pathways, including the production of pesticides, flavors, and dyes. Due to its reactive nature and potential hazards, proper safety protocols are paramount.

Safety information for 1,1,3-Trichloroacetone highlights its toxicity. It is classified as toxic if swallowed and inhalation, and can cause burns. Therefore, appropriate personal protective equipment (PPE), such as gloves, eye protection, and respiratory protection, must be used when handling this substance. Ventilation in work areas is also essential. When looking to purchase 1,1,3-Trichloroacetone, buyers should ensure that suppliers provide comprehensive safety data sheets (SDS) and adhere to strict safety guidelines during packaging and transportation. Sourcing from reputable China manufacturers who prioritize safety and quality is a key aspect of responsible chemical procurement.
