Chemical Structure
Description
The occurrence of Fudosteine Impurity 1 (Mixture of Diastereomers) is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Fudosteine Impurity 1 (Mixture of Diastereomers) (CAS 209665-22-5(free base)), a pharmacopoeial impurity reference standard (molecular formula C6H13NO4SC2HF3O2, MW 309.25 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Fudosteine Impurity 1 (Mixture of Diastereomers) (C6H13NO4SC2HF3O2) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Fudosteine Impurity 1 (Mixture of Diastereomers) 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.
