Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Bromo-4-hydroxy-5-nitrophenylsulphur pentafluoride.
3-Bromo-4-hydroxy-5-nitrophenylsulphur pentafluoride (CAS 1159512-28-3), molecular formula C6H3BrF5NO3S and molecular weight 344.05 g/mol, is a CATO reference standard with documented purity and traceability.
3-Bromo-4-hydroxy-5-nitrophenylsulphur pentafluoride (C6H3BrF5NO3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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), 3-Bromo-4-hydroxy-5-nitrophenylsulphur pentafluoride 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.
