Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Difelikefalin Impurity 32 Trifluoroacetic acid.
CATO supplies Difelikefalin Impurity 32 Trifluoroacetic acid (CAS CATO-C4X-304132), a pharmacopoeial impurity reference standard (molecular formula C72H104N14O11C2HF3O2, MW 1455.73 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Difelikefalin Impurity 32 Trifluoroacetic acid is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1455.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Difelikefalin Impurity 32 Trifluoroacetic acid 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.
