Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (4-Methyl-3-oxo-1-phenylpyrazolidin-4-yl)methyl acetate (CAS 80336-03-4), a certified reference material (molecular formula C13H16N2O3, MW 248.28 g/mol) for analytical method development and quality control.
Structurally, (4-Methyl-3-oxo-1-phenylpyrazolidin-4-yl)methyl acetate (C13H16N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 248.28 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).
As a certified reference material (CRM), (4-Methyl-3-oxo-1-phenylpyrazolidin-4-yl)methyl acetate 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.
