Adefovir Impurity 18 CAS CATO-C4X-115218

Description

Compared with other compounds in its class, the molecular weight of 1500.38 g/mol gives Adefovir Impurity 18 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Adefovir Impurity 18 (CAS CATO-C4X-115218) is a certified pharmaceutical impurity reference standard with the molecular formula C60H92N15O24P3 and a molecular weight of 1500.38 g/mol.

Adefovir Impurity 18 (C60H92N15O24P3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Adefovir Impurity 18 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.
