Chemical Structure
Description
The occurrence of (4Z)-4-(2-Phenylhydrazin-1-ylidene)-3,4-dihydro-1H-2-benzopyran-1,3-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (4Z)-4-(2-Phenylhydrazin-1-ylidene)-3,4-dihydro-1H-2-benzopyran-1,3-dione (CAS 339021-18-0), a certified reference material (molecular formula C15H10N2O3, MW 266.25 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (4Z)-4-(2-Phenylhydrazin-1-ylidene)-3,4-dihydro-1H-2-benzopyran-1,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.25 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).
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), (4Z)-4-(2-Phenylhydrazin-1-ylidene)-3,4-dihydro-1H-2-benzopyran-1,3-dione 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.
