Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 185.65 g/mol gives Metaraminol impound 105 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Metaraminol impound 105 (CAS CATO-C4X-2252105) is a certified pharmaceutical impurity reference standard with the molecular formula C9H12ClNO and a molecular weight of 185.65 g/mol.
Structurally, Metaraminol impound 105 (C9H12ClNO) contains a nitrogen-containing heterocyclic scaffold, 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 185.65 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.
