2-Bromo-4-methyl-1,3-benzothiazole(CAS: 73443-76-2)

2-Bromo-4-methyl-1,3-benzothiazole is a crystalline solid with a molecular weight of approximately 215.03 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and acetone. Chemically, it is relatively stable but can undergo substitution reactions, particularly with nucleophiles at the bromine or sulfur atom.

2-Bromo-4-methyl-1,3-benzothiazole is typically synthesized via the reaction of 4-methyl-1,3-benzothiazole with bromine in the presence of a Lewis acid catalyst such as iron(III) chloride. The synthesis involves bromination of the sulfur atom, leading to high selectivity and good yields.

2-Bromo-4-methyl-1,3-benzothiazole finds applications in the pharmaceutical and polymer industries. It is used as a precursor in the synthesis of various drugs and as an additive in polymer formulations to enhance thermal stability and flame retardancy.

When handling 2-Bromo-4-methyl-1,3-benzothiazole, it is important to use proper personal protective equipment (PPE) including gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to minimize inhalation risk. Spills should be handled carefully using appropriate materials, and the Material Safety Data Sheet (MSDS) should be consulted for detailed safety information.
