4-(2,6-Dichlorophenyl)-1h-pyrrole-3-carboxylic acid CAS 1096815-63-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(2,6-Dichlorophenyl)-1h-pyrrole-3-carboxylic acid.

4-(2,6-Dichlorophenyl)-1h-pyrrole-3-carboxylic acid (CAS 1096815-63-2) is a high-purity analytical reference standard with the molecular formula C11H7Cl2NO2 and a molecular weight of 256.08 g/mol.

4-(2,6-Dichlorophenyl)-1h-pyrrole-3-carboxylic acid (C11H7Cl2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 4-(2,6-Dichlorophenyl)-1h-pyrrole-3-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
