Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Cyclohexyl-1,2-dihydro-3H-pyrazol-3-one.
1-Cyclohexyl-1,2-dihydro-3H-pyrazol-3-one (CAS 35000-63-6), molecular formula C9H14N2O and molecular weight 166.22 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Cyclohexyl-1,2-dihydro-3H-pyrazol-3-one (C9H14N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 166.22 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), 1-Cyclohexyl-1,2-dihydro-3H-pyrazol-3-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.
