Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 3-amino-7-(trifluoromethyl)benzo[b]thiophene-2-carboxylate.

Methyl 3-amino-7-(trifluoromethyl)benzo[b]thiophene-2-carboxylate (CAS 2379918-54-2) is a high-purity analytical reference standard with the molecular formula C11H8F3NO2S and a molecular weight of 275.25 g/mol.

Structurally, Methyl 3-amino-7-(trifluoromethyl)benzo[b]thiophene-2-carboxylate (C11H8F3NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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 275.25 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
