Chemical Structure
Description
As a certified reference material (CRM), [3-(Trimethylammonium)propyl] Methanethiosulfonate Bromide 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.
[3-(Trimethylammonium)propyl] Methanethiosulfonate Bromide (CAS 220560-60-1), molecular formula C7H18NO2S2Br and molecular weight 292.25 g/mol, is a CATO reference standard with documented purity and traceability.
[3-(Trimethylammonium)propyl] Methanethiosulfonate Bromide (C7H18NO2S2Br) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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.
