Chemical Structure
Description
The occurrence of 3'-Butyl-3-ethyl-2'-thioxo-4,5-dihydro-2'H,3H-[2,5'-bithiazolylidene]-4'(3'H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3'-Butyl-3-ethyl-2'-thioxo-4,5-dihydro-2'H,3H-[2,5'-bithiazolylidene]-4'(3'H)-one (CAS 83783-59-9) is a high-purity analytical reference standard with the molecular formula C12H18N2OS3 and a molecular weight of 302.48 g/mol.
The molecular framework of 3'-Butyl-3-ethyl-2'-thioxo-4,5-dihydro-2'H,3H-[2,5'-bithiazolylidene]-4'(3'H)-one (C12H18N2OS3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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.
CATO manufactures 3'-Butyl-3-ethyl-2'-thioxo-4,5-dihydro-2'H,3H-[2,5'-bithiazolylidene]-4'(3'H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
