Adefovir (CAS 106941-25-7): Identity, Dipivoxil Distinction and Sourcing<\/h1>\n

Adefovir (CAS 106941-25-7; also known as PMEA) is a chemical substance listed in PubChem, CID 60172<\/a>, with molecular formula C8<\/sub>H12<\/sub>N5<\/sub>O4<\/sub>P. Correctly identifying the substance is essential when discussing pharmaceutical research or procurement.<\/p>\n

Adefovir and adefovir dipivoxil are distinct<\/h2>\n

The prescription product HEPSERA contains adefovir dipivoxil<\/strong>, a prodrug of adefovir. The official HEPSERA prescribing information on DailyMed<\/a> identifies that finished tablet product and its active ingredient.<\/p>\n

A label for adefovir dipivoxil tablets is not a dosing instruction for adefovir raw material. A raw-material listing cannot be substituted for a prescribed finished medicine. The compound, its prodrug and the formulated product must be distinguished in specifications, analytical methods and regulatory documents.<\/p>\n

Question<\/th>\nWhat to confirm<\/th>\n<\/tr>\n<\/thead>\n
Which substance is required?<\/th>\nAdefovir, CAS 106941-25-7, or a separately identified derivative\/prodrug<\/td>\n<\/tr>\n
Which material form?<\/th>\nExact form, grade, composition and applicable specification<\/td>\n<\/tr>\n
Which acceptance criteria?<\/th>\nIdentity tests, assay basis, related substances, water or drying measurement and relevant residuals<\/td>\n<\/tr>\n
Which use and market?<\/th>\nIntended professional application and destination-market requirements<\/td>\n<\/tr>\n
Which supporting records?<\/th>\nCurrent specification, batch COA, SDS and any separately required quality or regulatory documentation<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Interpreting medicine references<\/h2>\n

Medicine labeling describes the use, precautions and limitations of a particular approved product. It does not establish that every material sold under a related chemical name has the same quality, bioavailability, approval or clinical suitability. Product choice and treatment decisions require qualified clinical assessment and current prescribing information.<\/p>\n

This page does not recommend a medicine or a dose. Anyone already receiving treatment should discuss changes and questions with the prescribing healthcare professional.<\/p>\n

Reviewing the Longchang catalog record<\/h2>\n

The Longchang adefovir product record<\/a> contains historical catalog specification fields. Confirm the current limits and test procedures before relying on them for an order. A listed assay value does not establish compliance with every pharmacopoeia or authorize use in a finished medicine.<\/p>\n

When reviewing impurity results, compare the method, reporting threshold, reference standards and calculation basis as well as the numerical limit. Ensure that the COA identifies the actual lot and agrees with the specification named in the quotation.<\/p>\n
