Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,6-Dimethyl-1-phenyl-6,7-dihydro-1H-indazol-4(5H)-one.
6,6-Dimethyl-1-phenyl-6,7-dihydro-1H-indazol-4(5H)-one (CAS 43102-70-1), molecular formula C15H16N2O and molecular weight 240.30 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6,6-Dimethyl-1-phenyl-6,7-dihydro-1H-indazol-4(5H)-one (C15H16N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 240.30 g/mol, it falls into the medium-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), 6,6-Dimethyl-1-phenyl-6,7-dihydro-1H-indazol-4(5H)-one 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.
