4-(Chloromethyl)-2-phenyl-1,3-thiazole(CAS: 4771-31-7)

4-(Chloromethyl)-2-phenyl-1,3-thiazole is a yellow powder with a crystalline form. It has a molecular weight of approximately 240.6 g/mol. It exhibits low water solubility but has high solubility in organic solvents like ethanol and acetone. Chemically, it is stable under normal conditions but reacts with strong bases and reducing agents. It has a pKa of around 5.5, indicating it can act as a weak acid.

4-(Chloromethyl)-2-phenyl-1,3-thiazole is typically synthesized via the reaction of chloromethylbenzene with thiazole in the presence of an acid catalyst such as p-toluenesulfonic acid. The process involves the nucleophilic substitution of the chlorine atom by the thiazole ring, yielding a high yield of the desired product with good selectivity.

4-(Chloromethyl)-2-phenyl-1,3-thiazole finds applications in the pharmaceutical industry as a precursor for drug synthesis, in polymer science for the development of functional polymers, and in sensor technology for the detection of various gases. It is also used in the semiconductor industry for its reactivity and stability.

When handling 4-(Chloromethyl)-2-phenyl-1,3-thiazole, appropriate personal protective equipment (PPE) should be worn, including gloves, safety goggles, and a lab coat. It should be stored in a cool, dry place away from direct sunlight and heat sources. In case of spill, it should be handled in a well-ventilated area and with the aid of appropriate absorbents. Safety data sheets (SDS) should be consulted for detailed handling and disposal information.
