Chemical Structure
Description
The occurrence of 4,6-Dichloro-5-(2-phenyldiazenyl)-2-(propylthio)pyrimidine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,6-Dichloro-5-(2-phenyldiazenyl)-2-(propylthio)pyrimidine (CAS 946855-77-2), molecular formula C13H12Cl2N4S and molecular weight 327.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 4,6-Dichloro-5-(2-phenyldiazenyl)-2-(propylthio)pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 327.23 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4,6-Dichloro-5-(2-phenyldiazenyl)-2-(propylthio)pyrimidine 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.
