Chemical Structure
Description
The occurrence of (1S,2S)-2-(4-(5-((5-Chloropyridin-2-yl)thio)-1H-imidazol-4-yl)phenyl)cyclopropanecarboxylic acid is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(1S,2S)-2-(4-(5-((5-Chloropyridin-2-yl)thio)-1H-imidazol-4-yl)phenyl)cyclopropanecarboxylic acid (CAS 1242441-49-1), molecular formula C18H14ClN3O2S and molecular weight 371.84 g/mol, is a CATO reference standard with documented purity and traceability.
(1S,2S)-2-(4-(5-((5-Chloropyridin-2-yl)thio)-1H-imidazol-4-yl)phenyl)cyclopropanecarboxylic acid (C18H14ClN3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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.
