Chemical Structure
Description
1-(3-Chlorophenyl)-1H-pyrrole-2-carboxylic acid (CAS 952958-82-6), molecular formula C11H8ClNO2 and molecular weight 221.64 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(3-Chlorophenyl)-1H-pyrrole-2-carboxylic acid (C11H8ClNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-(3-Chlorophenyl)-1H-pyrrole-2-carboxylic 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.
