Chemical Structure

1-(4-Chlorophenyl)-4-(hydroxymethyl)-4-methylpyrazolidin-3-one CAS 83868-53-5 chemical structure

Description

As a certified reference material (CRM), 1-(4-Chlorophenyl)-4-(hydroxymethyl)-4-methylpyrazolidin-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.

CATO supplies 1-(4-Chlorophenyl)-4-(hydroxymethyl)-4-methylpyrazolidin-3-one (CAS 83868-53-5), a certified reference material (molecular formula C11H13ClN2O2, MW 240.69 g/mol) for analytical method development and quality control.

Structurally, 1-(4-Chlorophenyl)-4-(hydroxymethyl)-4-methylpyrazolidin-3-one (C11H13ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 240.69 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
