Chemical Structure

Mesna EP Impurity D CAS 45127-11-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 282.38 g/mol gives Mesna EP Impurity D distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Mesna EP Impurity D (CAS 45127-11-5) is a certified pharmaceutical impurity reference standard with the molecular formula C4H10O6S4 and a molecular weight of 282.38 g/mol.

Owing to a carbohydrate-derived structure, a sulfone group, Mesna EP Impurity D is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 282.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
