Chemical Structure

Argatroban Impurity 19 CAS 2423016-01-5 chemical structure

Description

Based on its molecular formula C23H35N5O6S, Argatroban Impurity 19 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 509.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Argatroban Impurity 19 (CAS 2423016-01-5) is a certified pharmaceutical impurity reference standard with the molecular formula C23H35N5O6S and a molecular weight of 509.62 g/mol.

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.
