{4-[(E)-2-phenyldiazen-1-yl]phenyl}thiourea CAS 4989-37-1 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

{4-[(E)-2-phenyldiazen-1-yl]phenyl}thiourea (CAS 4989-37-1) is a high-purity analytical reference standard with the molecular formula C13H12N4S and a molecular weight of 256.33 g/mol.

{4-[(E)-2-phenyldiazen-1-yl]phenyl}thiourea (C13H12N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

CATO manufactures {4-[(E)-2-phenyldiazen-1-yl]phenyl}thiourea 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.
