2,4-Dichlorobenzyl Alcohol EP Impurity G CAS 207974-13-8 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 2,4-Dichlorobenzyl Alcohol EP Impurity G.

CATO supplies 2,4-Dichlorobenzyl Alcohol EP Impurity G (CAS 207974-13-8), a pharmacopoeial impurity reference standard (molecular formula C14H10Cl4O, MW 336.04 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C14H10Cl4O, 2,4-Dichlorobenzyl Alcohol EP Impurity G contains a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 336.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures 2,4-Dichlorobenzyl Alcohol EP Impurity G 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.
