Chemical Structure

Fudosteine Impurity 31 CAS CATO-C4X-144731 chemical structure

Description

CATO supplies Fudosteine Impurity 31 (CAS CATO-C4X-144731), a pharmacopoeial impurity reference standard (molecular formula C9H19NO4S, MW 237.32 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Fudosteine Impurity 31 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.32 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.

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), Fudosteine Impurity 31 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.
