Chemical Structure

Tenofovir disoproxil Impurity 94 CAS 51260-39-0 chemical structure

Description

The molecular framework of Tenofovir disoproxil Impurity 94 (C4H6O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

CATO supplies Tenofovir disoproxil Impurity 94 (CAS 51260-39-0), a pharmacopoeial impurity reference standard (molecular formula C4H6O3, MW 102.09 g/mol) used for the identification and quantification of trace impurities in APIs.

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.

As a certified reference material (CRM), Tenofovir disoproxil Impurity 94 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.
