Chemical Structure

5-Trifluoromethyl-2-pyridinesulfonyl Chloride, 95%, 10% in Benzene CAS 174485-72-4 chemical structure

Description

The occurrence of 5-Trifluoromethyl-2-pyridinesulfonyl Chloride, 95%, 10% in Benzene is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Trifluoromethyl-2-pyridinesulfonyl Chloride, 95%, 10% in Benzene (CAS 174485-72-4), a certified reference material (molecular formula C6H3ClF3NO2S, MW 245.61 g/mol) for analytical method development and quality control.

5-Trifluoromethyl-2-pyridinesulfonyl Chloride, 95%, 10% in Benzene (C6H3ClF3NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, 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).

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.

As a certified reference material (CRM), 5-Trifluoromethyl-2-pyridinesulfonyl Chloride, 95%, 10% in Benzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
