Compared with other compounds in its class, the molecular weight of 141.18 g/mol gives N-Nitroso-N-methylaniline-d5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-Nitroso-N-methylaniline-d5 (CAS 1821341-18-7) is a high-purity analytical reference standard with the molecular formula C7H3D5N2O and a molecular weight of 141.18 g/mol.
Structurally, N-Nitroso-N-methylaniline-d5 (C7H3D5N2O) contains deuterium isotope labeling, an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 141.18 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
