Chemical Structure

Fluralaner impurity 40 CAS CATO-C4X-218040 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 Fluralaner impurity 40.

CATO supplies Fluralaner impurity 40 (CAS CATO-C4X-218040), a pharmacopoeial impurity reference standard (molecular formula C8H4Cl2F3NO, MW 258.02 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C8H4Cl2F3NO, Fluralaner impurity 40 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 258.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Fluralaner impurity 40 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.
