Chemical Structure

Methyl 4-fluorobenzo[b]thiophene-5-carboxylate CAS 313061-34-6 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 Methyl 4-fluorobenzo[b]thiophene-5-carboxylate.

Methyl 4-fluorobenzo[b]thiophene-5-carboxylate (CAS 313061-34-6), molecular formula C10H7FO2S and molecular weight 210.22 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl 4-fluorobenzo[b]thiophene-5-carboxylate (C10H7FO2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
