Description

As a certified reference material (CRM), 4-(Hydroxymethylene)-1,2-dimethylpyrazolidine-3,5-dione 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 4-(Hydroxymethylene)-1,2-dimethylpyrazolidine-3,5-dione (CAS 680987-19-3), a certified reference material (molecular formula C6H8N2O3, MW 156.14 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-(Hydroxymethylene)-1,2-dimethylpyrazolidine-3,5-dione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
