Rupatadine Impurity 22 1.5 hydrate CAS CATO-C4X-102722

Description

Compared with other compounds in its class, the molecular weight of 575.58 g/mol gives Rupatadine Impurity 22 1.5 hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Rupatadine Impurity 22 1.5 hydrate (CAS CATO-C4X-102722) is a certified pharmaceutical impurity reference standard with the molecular formula C33H34ClN4Cl1.5(H2O) and a molecular weight of 575.58 g/mol.

The molecular framework of Rupatadine Impurity 22 1.5 hydrate (C33H34ClN4Cl1.5(H2O)) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. 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 Rupatadine Impurity 22 1.5 hydrate 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.
