Description
The occurrence of Benzo(b)thiophene-2-carboxylic acid 1-benzothiophene-2-carboxylic acid benzothiophene-2-carboxylic acid benzo[b]thiophene-2-carboxylic acid 2-Benzo[b]thiophenecarboxylic acid 2-Carboxybenzothiophene Thianaphthene-2-carboxylic acid 6314-28-9 is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Benzo(b)thiophene-2-carboxylic acid 1-benzothiophene-2-carboxylic acid benzothiophene-2-carboxylic acid benzo[b]thiophene-2-carboxylic acid 2-Benzo[b]thiophenecarboxylic acid 2-Carboxybenzothiophene Thianaphthene-2-carboxylic acid 6314-28-9 (CAS 6314-28-9), a certified reference material (molecular formula C9H14O2S, MW 186.27 g/mol) for analytical method development and quality control.
Structurally, Benzo(b)thiophene-2-carboxylic acid 1-benzothiophene-2-carboxylic acid benzothiophene-2-carboxylic acid benzo[b]thiophene-2-carboxylic acid 2-Benzo[b]thiophenecarboxylic acid 2-Carboxybenzothiophene Thianaphthene-2-carboxylic acid 6314-28-9 (C9H14O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 186.27 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
