Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(Pyrimidin-2-ylamino)ethanol (CAS 1742-25-2) is a high-purity analytical reference standard with the molecular formula C6H9N3O and a molecular weight of 139.16 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-(Pyrimidin-2-ylamino)ethanol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
