Chemical Structure

Ruxolitinib Impurity 87 CAS CATO-C4X-205887 chemical structure

Description

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.

CATO supplies Ruxolitinib Impurity 87 (CAS CATO-C4X-205887), a pharmacopoeial impurity reference standard (molecular formula C8H17N3O, MW 171.24 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amide group, a hydroxyl group, an ether linkage, Ruxolitinib Impurity 87 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 171.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
