Chemical Structure

Tosufloxacin Impurity 1 DiHCl CAS 103831-11-4 chemical structure

Description

Owing to chlorine substitution, Tosufloxacin Impurity 1 DiHCl is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 122.60 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.

CATO supplies Tosufloxacin Impurity 1 DiHCl (CAS 103831-11-4), a pharmacopoeial impurity reference standard (molecular formula C4H10N2HCl, MW 122.60 g/mol) used for the identification and quantification of trace impurities in APIs.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

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.
