Chemical Structure

Maribavir Impurity 23 CAS 52689-56-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Maribavir Impurity 23.

CATO supplies Maribavir Impurity 23 (CAS 52689-56-2), a pharmacopoeial impurity reference standard (molecular formula C6H12O5, MW 164.16 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a carbohydrate-derived structure, Maribavir Impurity 23 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
