Chemical Structure
Description
The occurrence of Adefovir Dipivoxil is closely related to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Adefovir Dipivoxil (CAS 142340-99-6) is a high-purity analytical reference standard with the molecular formula C20H32N5O8P and a molecular weight of 501.47 g/mol.
Adefovir Dipivoxil (C20H32N5O8P) contains a flavonoid core, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Adefovir Dipivoxil 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.
