Chemical Structure

1-(3-Methoxypropyl)-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carbonitrile CAS 338399-18-1 chemical structure

Description

The occurrence of 1-(3-Methoxypropyl)-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carbonitrile is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-(3-Methoxypropyl)-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carbonitrile (CAS 338399-18-1), a certified reference material (molecular formula C9H11N3O3, MW 209.20 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-(3-Methoxypropyl)-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carbonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 209.20 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
