Chemical Structure
Description
The occurrence of N-(Pyrazolo[1,5-a][1,3,5]triazin-4-yl)hydroxylamine is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(Pyrazolo[1,5-a][1,3,5]triazin-4-yl)hydroxylamine (CAS 71774-62-4) is a high-purity analytical reference standard with the molecular formula C5H5N5O and a molecular weight of 151.13 g/mol.
Structurally, N-(Pyrazolo[1,5-a][1,3,5]triazin-4-yl)hydroxylamine (C5H5N5O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 151.13 g/mol, it falls into the medium-molecular-weight range. 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.
