4-Chloro-2-(2,5-dimethyl-1H-pyrrol-1-yl)benzoic acid CAS 335209-41-1 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 4-Chloro-2-(2,5-dimethyl-1H-pyrrol-1-yl)benzoic acid.

4-Chloro-2-(2,5-dimethyl-1H-pyrrol-1-yl)benzoic acid (CAS 335209-41-1) is a high-purity analytical reference standard with the molecular formula C13H12ClNO2 and a molecular weight of 249.69 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-Chloro-2-(2,5-dimethyl-1H-pyrrol-1-yl)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 249.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 4-Chloro-2-(2,5-dimethyl-1H-pyrrol-1-yl)benzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
