Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-([1,1'-Biphenyl]-2-yl)-2-((2,3-dihydrobenzo[b][1,4]dioxin-6-yl)thio)acetamide (CAS 852957-78-9), molecular formula C22H19NO3S and molecular weight 377.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-([1,1'-Biphenyl]-2-yl)-2-((2,3-dihydrobenzo[b][1,4]dioxin-6-yl)thio)acetamide (C22H19NO3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 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), N-([1,1'-Biphenyl]-2-yl)-2-((2,3-dihydrobenzo[b][1,4]dioxin-6-yl)thio)acetamide 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.
