Chemical Structure
Description
The occurrence of 2-(2-Methylpyrimidin-5-yl)ethan-1-amine is closely related to a nitrile group, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(2-Methylpyrimidin-5-yl)ethan-1-amine (CAS 933685-75-7), molecular formula C7H11N3 and molecular weight 137.18 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, an aromatic ring system, 2-(2-Methylpyrimidin-5-yl)ethan-1-amine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
