Chemical Structure

1-(Isocyano(tosyl)methyl)-3-(trifluoromethyl)benzene CAS 263389-45-3 chemical structure

Description

The occurrence of 1-(Isocyano(tosyl)methyl)-3-(trifluoromethyl)benzene is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-(Isocyano(tosyl)methyl)-3-(trifluoromethyl)benzene (CAS 263389-45-3), a certified reference material (molecular formula C16H12F3NO2S, MW 339.33 g/mol) for analytical method development and quality control.

1-(Isocyano(tosyl)methyl)-3-(trifluoromethyl)benzene (C16H12F3NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
