Chemical Structure
Description
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 supplies Prasugrel Impurity N16 (CAS 1373350-57-2), a pharmacopoeial impurity reference standard (molecular formula C11H11Br2, MW 338.01 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to bromine substitution, an aromatic ring system, Prasugrel Impurity N16 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 338.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures Prasugrel Impurity N16 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.
