3-Chloro-2,2-bis(chloromethyl)propanoic acid(CAS: 17831-70-8)

3-Chloro-2,2-bis(chloromethyl)propanoic acid (CAS: 17831-70-8) is a crystalline solid with a molecular weight of approximately 313.95 g/mol. It is poorly soluble in water but soluble in organic solvents such as ethanol and acetone. The compound exhibits strong reactivity due to the presence of multiple electrophilic chloromethyl groups, making it prone to nucleophilic substitution reactions.

3-Chloro-2,2-bis(chloromethyl)propanoic acid is typically synthesized through a series of chlorination and acylation reactions. The process involves the chlorination of 2,2-bis(chloromethyl)propane followed by acylation with chloroacetyl chloride. The reaction is typically performed under anhydrous conditions to avoid side reactions. Yield and selectivity can be improved by using appropriate catalysts.

3-Chloro-2,2-bis(chloromethyl)propanoic acid (CAS: 17831-70-8) finds applications in the pharmaceutical industry for the synthesis of certain intermediates, as well as in the sensor industry for the development of gas sensors. It can also be used in the semiconductor industry as a component in photoresists and other specialty chemicals.

When handling 3-Chloro-2,2-bis(chloromethyl)propanoic acid (CAS: 17831-70-8), it is essential to wear appropriate personal protective equipment (PPE) including gloves, safety goggles, and a lab coat. Storage should be in a fume hood or well-ventilated area. Spills should be handled using appropriate containment and neutralization techniques. Always refer to the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
