Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 155.22 g/mol gives Dotinurad Impurity 128 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dotinurad Impurity 128 (CAS CATO-C4X-2494128) is a certified pharmaceutical impurity reference standard with the molecular formula C7H9NOS and a molecular weight of 155.22 g/mol.
Dotinurad Impurity 128 (C7H9NOS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Dotinurad Impurity 128 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.
