o-((1-Methyl-1h-pyrazol-4-yl)methyl)hydroxylamine CAS 791572-69-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including o-((1-Methyl-1h-pyrazol-4-yl)methyl)hydroxylamine.

o-((1-Methyl-1h-pyrazol-4-yl)methyl)hydroxylamine (CAS 791572-69-5), molecular formula C5H9N3O and molecular weight 127.14 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, o-((1-Methyl-1h-pyrazol-4-yl)methyl)hydroxylamine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 127.14 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.
