Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8-(2-(1-(4-Hydroxyphenyl)ethylidene)hydrazinyl)-7-isobutyl-3-methyl-3,7-dihydro-1H-purine-2,6-dione.
8-(2-(1-(4-Hydroxyphenyl)ethylidene)hydrazinyl)-7-isobutyl-3-methyl-3,7-dihydro-1H-purine-2,6-dione (CAS 682776-57-4), molecular formula C18H22N6O3 and molecular weight 370.41 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 8-(2-(1-(4-Hydroxyphenyl)ethylidene)hydrazinyl)-7-isobutyl-3-methyl-3,7-dihydro-1H-purine-2,6-dione (C18H22N6O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 370.41 g/mol, it falls into the moderately-high-molecular-weight range. 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), 8-(2-(1-(4-Hydroxyphenyl)ethylidene)hydrazinyl)-7-isobutyl-3-methyl-3,7-dihydro-1H-purine-2,6-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.
