Chemical Structure
Description
The occurrence of 4-Bromo-N-[(4-ethyl-5-{[(3-methoxyphenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methyl]benzene-1-sulfonamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Bromo-N-[(4-ethyl-5-{[(3-methoxyphenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methyl]benzene-1-sulfonamide (CAS 338794-57-3), a certified reference material (molecular formula C19H21BrN4O3S2, MW 497.43 g/mol) for analytical method development and quality control.
4-Bromo-N-[(4-ethyl-5-{[(3-methoxyphenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methyl]benzene-1-sulfonamide (C19H21BrN4O3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine 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.
As a certified reference material (CRM), 4-Bromo-N-[(4-ethyl-5-{[(3-methoxyphenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methyl]benzene-1-sulfonamide 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.
