Chemical Structure

7-Chloroquinolin-4-yl trifluoromethanesulfonate CAS 202923-78-2 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 7-Chloroquinolin-4-yl trifluoromethanesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

7-Chloroquinolin-4-yl trifluoromethanesulfonate (CAS 202923-78-2) is a high-purity analytical reference standard with the molecular formula C10H5ClF3NO3S and a molecular weight of 311.66 g/mol.

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.

CATO manufactures 7-Chloroquinolin-4-yl trifluoromethanesulfonate 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.
