Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Fluorobenzoic-d4 Acid.
CATO supplies 4-Fluorobenzoic-d4 Acid (CAS 93111-25-2), a certified reference material (molecular formula C7HD4FO2, MW 144.14 g/mol) for analytical method development and quality control.
The molecular framework of 4-Fluorobenzoic-d4 Acid (C7HD4FO2) is characterized by deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Fluorobenzoic-d4 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.
