Chemical Structure

1-(2,3-Dimethyltetrahydropyrimidin-1(2H)-yl)ethanone CAS 191990-63-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2,3-Dimethyltetrahydropyrimidin-1(2H)-yl)ethanone.

1-(2,3-Dimethyltetrahydropyrimidin-1(2H)-yl)ethanone (CAS 191990-63-3) is a high-purity analytical reference standard with the molecular formula C8H16N2O and a molecular weight of 156.23 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, 1-(2,3-Dimethyltetrahydropyrimidin-1(2H)-yl)ethanone is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
