Chemical Structure

N-nitroso-exametazime CAS CATO-C4X-34141 chemical structure

Description

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.

N-nitroso-exametazime (CAS CATO-C4X-34141) is a high-purity analytical reference standard with the molecular formula C13H26N5O3 and a molecular weight of 300.38 g/mol.

Structurally, N-nitroso-exametazime (C13H26N5O3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 300.38 g/mol, it falls into the moderately-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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
