Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-chloranyl-3-fluoranyl-phenyl)ethanoic acid 2-(4-chloro-3-fluorophenyl)acetic acid 865451-00-9 A841715.
2-(4-chloranyl-3-fluoranyl-phenyl)ethanoic acid 2-(4-chloro-3-fluorophenyl)acetic acid 865451-00-9 A841715 (CAS 865451-00-9), molecular formula C8H6ClFO2 and molecular weight 188.58 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-chloranyl-3-fluoranyl-phenyl)ethanoic acid 2-(4-chloro-3-fluorophenyl)acetic acid 865451-00-9 A841715 (C8H6ClFO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 2-(4-chloranyl-3-fluoranyl-phenyl)ethanoic acid 2-(4-chloro-3-fluorophenyl)acetic acid 865451-00-9 A841715 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.
