Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies 259139-19-0 3,3-Diethyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin 3,4-(2 inverted exclamation marka,2 inverted exclamation marka-Diethylpropylene)dioxythiophene EDOT analog (CAS 259139-19-0), a certified reference material (molecular formula C11H20O2S, MW 216.34 g/mol) for analytical method development and quality control.

The molecular framework of 259139-19-0 3,3-Diethyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin 3,4-(2 inverted exclamation marka,2 inverted exclamation marka-Diethylpropylene)dioxythiophene EDOT analog (C11H20O2S) is characterized by a sulfone group, a carboxylic acid 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
