Chemical Structure

Argatroban Impurity 111 CAS CATO-C4X-1007111 chemical structure

Description

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.

Argatroban Impurity 111 (CAS CATO-C4X-1007111) is a certified pharmaceutical impurity reference standard with the molecular formula C16H21N5O4S and a molecular weight of 379.43 g/mol.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Argatroban Impurity 111 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 379.43 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.
