3-(propan-2-yl)-2-sulfanyl-3,4-dihydroquinazolin-4-one CAS 21038-90-4

Description

As a certified reference material (CRM), 3-(propan-2-yl)-2-sulfanyl-3,4-dihydroquinazolin-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies 3-(propan-2-yl)-2-sulfanyl-3,4-dihydroquinazolin-4-one (CAS 21038-90-4), a certified reference material (molecular formula C11H20N2OS, MW 228.35 g/mol) for analytical method development and quality control.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-(propan-2-yl)-2-sulfanyl-3,4-dihydroquinazolin-4-one is typically white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 228.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
