Chemical Structure

1,3,5-Triphenylformazan CAS 531-52-2 chemical structure

Description

The occurrence of 1,3,5-Triphenylformazan is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1,3,5-Triphenylformazan (CAS 531-52-2), a certified reference material (molecular formula C19H16N4, MW 300.36 g/mol) for analytical method development and quality control.

1,3,5-Triphenylformazan (C19H16N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 1,3,5-Triphenylformazan 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.
