Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Isopropyl 3-chloro-5-methoxy-6-methylbenzo[b]thiophene-2-carboxylate.
CATO supplies Isopropyl 3-chloro-5-methoxy-6-methylbenzo[b]thiophene-2-carboxylate (CAS 1056047-21-2), a certified reference material (molecular formula C14H15ClO3S, MW 298.79 g/mol) for analytical method development and quality control.
Structurally, Isopropyl 3-chloro-5-methoxy-6-methylbenzo[b]thiophene-2-carboxylate (C14H15ClO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 298.79 g/mol, it falls into the medium-molecular-weight range. 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).
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.
