Description
2-((2-Chloro-6-fluorobenzyl)thio)-1-(3-methoxyphenyl)-3a,4,6,6a-tetrahydro-1H-thieno[3,4-d]imidazole 5,5-dioxide (CAS 921158-60-3), molecular formula C19H18ClFN2O3S2 and molecular weight 440.94 g/mol, is a CATO reference standard with documented purity and traceability.
2-((2-Chloro-6-fluorobenzyl)thio)-1-(3-methoxyphenyl)-3a,4,6,6a-tetrahydro-1H-thieno[3,4-d]imidazole 5,5-dioxide (C19H18ClFN2O3S2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 2-((2-Chloro-6-fluorobenzyl)thio)-1-(3-methoxyphenyl)-3a,4,6,6a-tetrahydro-1H-thieno[3,4-d]imidazole 5,5-dioxide 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.
