Chemical Structure
Description
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 supplies (1R,2R)-2-(4-Chlorophenyl)cyclopropanecarboxylic Acid (CAS 31501-86-7), a certified reference material (molecular formula C10H9ClO2, MW 196.63 g/mol) for analytical method development and quality control.
The molecular framework of (1R,2R)-2-(4-Chlorophenyl)cyclopropanecarboxylic Acid (C10H9ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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).
As a certified reference material (CRM), (1R,2R)-2-(4-Chlorophenyl)cyclopropanecarboxylic 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.
