Chemical Structure

N-methylethylenediamine CAS 109-81-9 chemical structure

Description

N-methylethylenediamine (CAS 109-81-9) is a high-purity analytical reference standard with the molecular formula C3H10N2 and a molecular weight of 74.12 g/mol.

Structurally, N-methylethylenediamine (C3H10N2) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 74.12 g/mol, it falls into the low-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.

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.
