Chemical Structure
Description
The occurrence of 3,4-Difluoro-2,5-bis(trimethylsilyl)thiophene is closely related to sulfur-containing functionality, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3,4-Difluoro-2,5-bis(trimethylsilyl)thiophene (CAS 347838-12-4), a certified reference material (molecular formula C10H18F2SSi2, MW 264.48 g/mol) for analytical method development and quality control.
The molecular framework of 3,4-Difluoro-2,5-bis(trimethylsilyl)thiophene (C10H18F2SSi2) is characterized by sulfur-containing functionality, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 3,4-Difluoro-2,5-bis(trimethylsilyl)thiophene 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.
