Chemical Structure

Mupirocin EP Impurity D CAS 71087-97-3 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Mupirocin EP Impurity D is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 500.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Mupirocin EP Impurity D (CAS 71087-97-3) is a certified pharmaceutical impurity reference standard with the molecular formula C26H44O9 and a molecular weight of 500.62 g/mol.

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.
