3-(2-(Prop-2-yn-1-ylthio)pyrimidin-4-yl)-1-(p-tolyl)pyridazin-4(1H)-one CAS 478077-71-3

Description

The occurrence of 3-(2-(Prop-2-yn-1-ylthio)pyrimidin-4-yl)-1-(p-tolyl)pyridazin-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.

CATO supplies 3-(2-(Prop-2-yn-1-ylthio)pyrimidin-4-yl)-1-(p-tolyl)pyridazin-4(1H)-one (CAS 478077-71-3), a certified reference material (molecular formula C18H14N4OS, MW 334.39 g/mol) for analytical method development and quality control.

Structurally, 3-(2-(Prop-2-yn-1-ylthio)pyrimidin-4-yl)-1-(p-tolyl)pyridazin-4(1H)-one (C18H14N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 334.39 g/mol, it falls into the moderately-high-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.
