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 3-(2-((4-Chlorophenyl)sulfonamido)phenoxy)thiophene-2-carboxylic acid.
3-(2-((4-Chlorophenyl)sulfonamido)phenoxy)thiophene-2-carboxylic acid (CAS 900019-15-0), molecular formula C17H12ClNO5S2 and molecular weight 409.86 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(2-((4-Chlorophenyl)sulfonamido)phenoxy)thiophene-2-carboxylic acid (C17H12ClNO5S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 409.86 g/mol, it falls into the moderately-high-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.
