Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl Clofibrate-d4 (4-chlorophenyl-d4).
Ethyl Clofibrate-d4 (4-chlorophenyl-d4) (CAS 1189654-03-2) is a high-purity analytical reference standard with the molecular formula C12H11D4ClO3 and a molecular weight of 246.72 g/mol.
The molecular framework of Ethyl Clofibrate-d4 (4-chlorophenyl-d4) (C12H11D4ClO3) is characterized by deuterium isotope labeling, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Ethyl Clofibrate-d4 (4-chlorophenyl-d4) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
