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.
5-((2-Chloro-6-fluorobenzyl)thio)-8,9-dimethoxy-2-methyl-[1,2,4]triazolo[1,5-c]quinazoline (CAS 860611-08-1), molecular formula C19H16ClFN4O2S and molecular weight 418.87 g/mol, is a CATO reference standard with documented purity and traceability.
5-((2-Chloro-6-fluorobenzyl)thio)-8,9-dimethoxy-2-methyl-[1,2,4]triazolo[1,5-c]quinazoline (C19H16ClFN4O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 5-((2-Chloro-6-fluorobenzyl)thio)-8,9-dimethoxy-2-methyl-[1,2,4]triazolo[1,5-c]quinazoline 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.
