Chemical Structure
Description
The occurrence of (E)-2,5-Dimethyl-3-(pent-1-en-1-yl)pyrazine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (E)-2,5-Dimethyl-3-(pent-1-en-1-yl)pyrazine (CAS 143901-57-9), a certified reference material (molecular formula C11H16N2, MW 176.26 g/mol) for analytical method development and quality control.
Structurally, (E)-2,5-Dimethyl-3-(pent-1-en-1-yl)pyrazine (C11H16N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 176.26 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
