As a manufacturer and supplier of this key intermediate, we provide a detailed overview of its critical specifications.

Chemical Identity and Properties

The compound is chemically known as 5-Chloro-2-methylbenzothiazole, with synonyms such as 2-Methyl-5-chlorobenzothiazole. Its molecular formula is C8H6ClNS, and it has a molecular weight of 183.66 g/mol. Understanding these basic identifiers is the first step for any scientist or procurement manager seeking to buy or use this chemical.

Key Technical Specifications

  • Appearance: Typically described as a white to off-white crystalline powder. This physical characteristic is the first visual indicator of product quality. Variations in color or form may suggest impurity or improper handling.
  • Purity: This is arguably the most critical specification for pharmaceutical intermediates. 5-Chloro-2-methylbenzothiazole is commonly supplied with a purity of >99.5% as determined by Gas Chromatography (GC). High purity ensures minimal interference in subsequent synthesis steps and contributes to the quality of the final product. Buyers should always request a Certificate of Analysis (CoA) from their supplier to confirm this.
  • Melting Point: While not always explicitly stated for all specifications, literature often cites a melting point range of 65-70°C. This physical property is another indicator of purity and consistency.
  • Boiling Point: The boiling point is reported around 147°C at 15 mmHg, providing data relevant to distillation or high-temperature reactions.
  • Solubility: Information on solubility in common solvents is crucial for formulation and reaction design. While not detailed in all product sheets, this data is often available upon request from manufacturers.

Handling and Storage Recommendations

Proper handling and storage are essential to maintain the quality and integrity of 5-Chloro-2-methylbenzothiazole. It should be stored in tightly sealed containers in a cool, dry, and well-ventilated place, protected from light and moisture. Adherence to these guidelines by both the manufacturer and the end-user is vital, especially when purchasing in bulk for commercial production.
