Chemical Structure

N-Ethyl-N-(3-methylphenyl)propane-1,3-diamine CAS 83566-92-1 chemical structure

Description

N-Ethyl-N-(3-methylphenyl)propane-1,3-diamine (CAS 83566-92-1), molecular formula C12H20N2 and molecular weight 192.30 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-Ethyl-N-(3-methylphenyl)propane-1,3-diamine (C12H20N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 192.30 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
