Potassium 4-chloro-2-(thiophene-2-carboxamido)benzoate CAS 1011405-11-0

Description

Compared with other compounds in its class, the molecular weight of 319.80 g/mol gives Potassium 4-chloro-2-(thiophene-2-carboxamido)benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Potassium 4-chloro-2-(thiophene-2-carboxamido)benzoate (CAS 1011405-11-0) is a high-purity analytical reference standard with the molecular formula C12H7ClNO3SK and a molecular weight of 319.80 g/mol.

The molecular framework of Potassium 4-chloro-2-(thiophene-2-carboxamido)benzoate (C12H7ClNO3SK) is characterized by a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. 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.
