Methyl thiazole-5-carboxylate
Methyl thiazole-5-carboxylate (CAS 14527-44-7) is a heterocyclic building block with the molecular formula C5H5NO2S and a molar mass of 143.16 g/mol. It is the methyl ester of thiazole-5-carboxylic acid, combining a sulfur- and nitrogen-bearing thiazole ring with a reactive ester group. Used primarily in chemical synthesis and pharmaceutical-intermediate research, it serves as a versatile C3-to-C7 scaffold. Tech Serve Solutions supplies and exports this thiazole reagent to research and manufacturing customers worldwide.

Heterocyclic building block
Functions as a thiazole-based scaffold in multistep organic synthesis, providing a pre-formed ring system that can be further elaborated at the ester and ring positions.
Pharmaceutical intermediate research
The thiazole motif is common in medicinal chemistry, making this ester a useful intermediate for exploratory synthesis of active compounds and analogues. Specific end-uses depend on the customer's own route.
Ester chemistry and functional-group conversion
The methyl ester is a convenient handle for hydrolysis to the carboxylic acid, transesterification, or conversion to amides and other derivatives during route development.
Laboratory reagent and reference material
Supplied as a defined small-molecule reagent for synthetic, analytical and method-development work in research laboratories.
