Chemical Structure
Description
The occurrence of 5-[(Z)-2-(3-Methylphenyl)diazen-1-yl]-2-(pyridin-2-yl)-4-(thiophen-2-yl)pyrimidine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-[(Z)-2-(3-Methylphenyl)diazen-1-yl]-2-(pyridin-2-yl)-4-(thiophen-2-yl)pyrimidine (CAS 339279-58-2), a certified reference material (molecular formula C20H15N5S, MW 357.43 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 5-[(Z)-2-(3-Methylphenyl)diazen-1-yl]-2-(pyridin-2-yl)-4-(thiophen-2-yl)pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 357.43 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.
CATO manufactures 5-[(Z)-2-(3-Methylphenyl)diazen-1-yl]-2-(pyridin-2-yl)-4-(thiophen-2-yl)pyrimidine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
