Chemical Structure
Description
The molecular framework of 4,4'-Dimethyl-[2,2'-bithiophene]-5,5'-dicarbaldehyde (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.
4,4'-Dimethyl-[2,2'-bithiophene]-5,5'-dicarbaldehyde (CAS 91544-06-8) is a high-purity analytical reference standard with the molecular formula C12H10O2S2 and a molecular weight of 250.34 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4,4'-Dimethyl-[2,2'-bithiophene]-5,5'-dicarbaldehyde 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.
