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 Fudosteine Impurity 1 Disodium Salt.
CATO supplies Fudosteine Impurity 1 Disodium Salt (CAS CATO-C4X-144744), a pharmacopoeial impurity reference standard (molecular formula C10H16NO7SNa, MW 317.29 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 1 Disodium Salt is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 317.29 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.
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.
