Chemical Structure

Ethyl 2-(2-chloroacetamido)-4,5-dihydronaphtho[1,2-b]thiophene-3-carboxylate CAS 497230-86-1 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 Ethyl 2-(2-chloroacetamido)-4,5-dihydronaphtho[1,2-b]thiophene-3-carboxylate.

CATO supplies Ethyl 2-(2-chloroacetamido)-4,5-dihydronaphtho[1,2-b]thiophene-3-carboxylate (CAS 497230-86-1), a certified reference material (molecular formula C17H16ClNO3S, MW 349.83 g/mol) for analytical method development and quality control.

Structurally, Ethyl 2-(2-chloroacetamido)-4,5-dihydronaphtho[1,2-b]thiophene-3-carboxylate (C17H16ClNO3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 349.83 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
