Chemical Structure

Adefovir Dipivoxil Impurity 25 CAS 83881-47-4 chemical structure

Description

The occurrence of Adefovir Dipivoxil Impurity 25 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Adefovir Dipivoxil Impurity 25 (CAS 83881-47-4), molecular formula C5H9ClO3 and molecular weight 152.58 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H9ClO3, Adefovir Dipivoxil Impurity 25 contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 152.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Adefovir Dipivoxil Impurity 25 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
