n1-((3-Bromothiophen-2-yl)methyl)-n2,n2-diethylethane-1,2-diamine CAS 1249779-03-0

Description

The occurrence of n1-((3-Bromothiophen-2-yl)methyl)-n2,n2-diethylethane-1,2-diamine is closely related to a nitrile group, sulfur-containing functionality, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

n1-((3-Bromothiophen-2-yl)methyl)-n2,n2-diethylethane-1,2-diamine (CAS 1249779-03-0), molecular formula C11H19BrN2S and molecular weight 291.25 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, n1-((3-Bromothiophen-2-yl)methyl)-n2,n2-diethylethane-1,2-diamine (C11H19BrN2S) contains a nitrile group, sulfur-containing functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 291.25 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.
