Chemical Structure

Midecamycin Impurity 20 CAS CATO-C4X-312220 chemical structure

Description

Structurally, Midecamycin Impurity 20 (C22H43NO8C19H34O2C2H6O2C3H6OC2H4OCH4OCH2O) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 970.33 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Midecamycin Impurity 20 (CAS CATO-C4X-312220) is a certified pharmaceutical impurity reference standard with the molecular formula C22H43NO8C19H34O2C2H6O2C3H6OC2H4OCH4OCH2O and a molecular weight of 970.33 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.
