Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4-Dimethyl-1-phenylpyrazolidin-3-one.
CATO supplies 4,4-Dimethyl-1-phenylpyrazolidin-3-one (CAS 2654-58-2), a certified reference material (molecular formula C33H37FO7S2, MW 628.77 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, 4,4-Dimethyl-1-phenylpyrazolidin-3-one is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 628.77 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 4,4-Dimethyl-1-phenylpyrazolidin-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.
