1-(3,5-Dimethyl-1H-pyrazol-1-yl)ethan-1-one CAS 10199-63-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3,5-Dimethyl-1H-pyrazol-1-yl)ethan-1-one.

1-(3,5-Dimethyl-1H-pyrazol-1-yl)ethan-1-one (CAS 10199-63-0), molecular formula C7H10N2O and molecular weight 138.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 1-(3,5-Dimethyl-1H-pyrazol-1-yl)ethan-1-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.17 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.
