Chemical Structure

Ethylene-d4-diamine CAS 37164-19-5 chemical structure

Description

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.

Ethylene-d4-diamine (CAS 37164-19-5), molecular formula C2H4D4N2 and molecular weight 64.12 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Ethylene-d4-diamine (C2H4D4N2) contains deuterium isotope labeling, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 64.12 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.

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.
