Paricalcitol Impurity 24 CAS CATO-C4X-138724 chemical structure

Description

Paricalcitol Impurity 24 (CAS CATO-C4X-138724) is a certified pharmaceutical impurity reference standard with the molecular formula C19H32O and a molecular weight of 276.46 g/mol.

Based on its molecular formula C19H32O, Paricalcitol Impurity 24 contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 276.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Paricalcitol Impurity 24 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.
