Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
20966-34-1 Butadiene sulfone-2,2,5,5-d4 (CAS 20966-34-1), molecular formula C4H2D4O2S and molecular weight 122.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 20966-34-1 Butadiene sulfone-2,2,5,5-d4 (C4H2D4O2S) is characterized by deuterium isotope labeling, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 20966-34-1 Butadiene sulfone-2,2,5,5-d4 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.
