Description
CATO manufactures Eldecalcitol Impurity 8 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.
Eldecalcitol Impurity 8 (CAS CATO-C4X-21408) is a certified pharmaceutical impurity reference standard with the molecular formula C30H63IO5Si3 and a molecular weight of 714.98 g/mol.
Eldecalcitol Impurity 8 (C30H63IO5Si3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
