Chemical Structure

Minodronic Impurity 35 CAS 35752-46-6 chemical structure

Description

The occurrence of Minodronic Impurity 35 is closely related to a carbohydrate-derived structure, a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Minodronic Impurity 35 (CAS 35752-46-6) is a certified pharmaceutical impurity reference standard with the molecular formula C4H9O4P and a molecular weight of 152.09 g/mol.

Structurally, Minodronic Impurity 35 (C4H9O4P) contains a carbohydrate-derived structure, a phosphate ester group. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 152.09 g/mol, it falls into the medium-molecular-weight range.

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.
