5,6-Bis((E)-benzylideneamino)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one CAS 1533426-72-0

Description

The occurrence of 5,6-Bis((E)-benzylideneamino)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5,6-Bis((E)-benzylideneamino)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (CAS 1533426-72-0), molecular formula C18H16N4OS and molecular weight 336.41 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 5,6-Bis((E)-benzylideneamino)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.41 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.
