Chemical Structure
Description
The occurrence of (E)-N,N-dimethyl-2-(pyrimidin-2-yl)ethen-1-amine 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.
(E)-N,N-dimethyl-2-(pyrimidin-2-yl)ethen-1-amine (CAS 137475-75-3) is a high-purity analytical reference standard with the molecular formula C8H11N3 and a molecular weight of 149.19 g/mol.
Structurally, (E)-N,N-dimethyl-2-(pyrimidin-2-yl)ethen-1-amine (C8H11N3) 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 149.19 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
