Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 174.59 g/mol gives Minoxidil Impurity 68 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Minoxidil Impurity 68 (CAS CATO-C4X-170068) is a certified pharmaceutical impurity reference standard with the molecular formula C5H7ClN4O and a molecular weight of 174.59 g/mol.
Structurally, Minoxidil Impurity 68 (C5H7ClN4O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 174.59 g/mol, it falls into the medium-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.
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.
