Chemical Structure
Description
n,5-Dimethyl-1,2-oxazol-3-amine (CAS 55809-40-0) is a high-purity analytical reference standard with the molecular formula C5H8N2O and a molecular weight of 112.13 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, n,5-Dimethyl-1,2-oxazol-3-amine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 112.13 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).
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.
