Chemical Structure

N-(7H-Purin-6-yl)hydroxylamine CAS 5667-20-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 151.13 g/mol gives N-(7H-Purin-6-yl)hydroxylamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-(7H-Purin-6-yl)hydroxylamine (CAS 5667-20-9), molecular formula C5H5N5O and molecular weight 151.13 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H5N5O, N-(7H-Purin-6-yl)hydroxylamine contains an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 151.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
