Chemical Structure

1-(3-Hydroxypropyl)-4-sulfanylidene-1,2,3,4,5,6,7,8-octahydroquinazolin-2-one CAS 920159-05-3 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-(3-Hydroxypropyl)-4-sulfanylidene-1,2,3,4,5,6,7,8-octahydroquinazolin-2-one.

CATO supplies 1-(3-Hydroxypropyl)-4-sulfanylidene-1,2,3,4,5,6,7,8-octahydroquinazolin-2-one (CAS 920159-05-3), a certified reference material (molecular formula C11H16N2O2S, MW 240.32 g/mol) for analytical method development and quality control.

Structurally, 1-(3-Hydroxypropyl)-4-sulfanylidene-1,2,3,4,5,6,7,8-octahydroquinazolin-2-one (C11H16N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 240.32 g/mol, it falls into the medium-molecular-weight range. 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.
