Chemical Structure
Description
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, Thiophene-2-carboximidic acid methyl esterhydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies Thiophene-2-carboximidic acid methyl esterhydrochloride (CAS 54610-49-0), a certified reference material (molecular formula C6H7NOSHCl, MW 177.65 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
