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 Linaclotide Impurity 20 (CAS CATO-C4X-210620), a pharmacopoeial impurity reference standard (molecular formula C59H79N15O21S6, MW 1526.73 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Linaclotide Impurity 20 (C59H79N15O21S6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 28.0, corresponding to approximately 28 ring(s) or double-bond equivalent(s). With a molecular weight of 1526.73 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures Linaclotide Impurity 20 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.
