Chemical Structure
Description
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.
(3,4-Difluorophenyl)(5-methylthiophen-2-yl)methanol (CAS 1249578-63-9) is a high-purity analytical reference standard with the molecular formula C12H10F2OS and a molecular weight of 240.27 g/mol.
(3,4-Difluorophenyl)(5-methylthiophen-2-yl)methanol (C12H10F2OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures (3,4-Difluorophenyl)(5-methylthiophen-2-yl)methanol 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.
