Chemical Structure
Description
CATO supplies 5-Chloro-2-(1H-pyrrol-1-yl)phenol (CAS 590394-78-8), a certified reference material (molecular formula C10H8ClNO, MW 193.63 g/mol) for analytical method development and quality control.
The molecular framework of 5-Chloro-2-(1H-pyrrol-1-yl)phenol (C10H8ClNO) 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).
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), 5-Chloro-2-(1H-pyrrol-1-yl)phenol 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.
