Chemical Structure
Description
The occurrence of 1,3-Diethynyl-5-(trifluoromethyl)benzene is closely related to fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,3-Diethynyl-5-(trifluoromethyl)benzene (CAS 1622871-80-0), a certified reference material (molecular formula C11H5F3, MW 194.15 g/mol) for analytical method development and quality control.
1,3-Diethynyl-5-(trifluoromethyl)benzene (C11H5F3) contains 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 1,3-Diethynyl-5-(trifluoromethyl)benzene 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.
