Vonoprazan Impurity 89 CAS 1224739-02-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Vonoprazan Impurity 89.

CATO supplies Vonoprazan Impurity 89 (CAS 1224739-02-9), a pharmacopoeial impurity reference standard (molecular formula C8H5Br2FO, MW 295.93 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, Vonoprazan Impurity 89 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 295.93 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
