Chemical Structure
Description
1,4-Di(2-thienyl)-1,4-butanedione (CAS 13669-05-1), molecular formula C12H10O2S2 and molecular weight 250.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,4-Di(2-thienyl)-1,4-butanedione (C12H10O2S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 1,4-Di(2-thienyl)-1,4-butanedione 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.
