Description
As a certified reference material (CRM), [2-(Trimethylammonium)ethyl]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.
[2-(Trimethylammonium)ethyl]methanethiosulfonate Bromide (CAS 91774-25-3) is a high-purity analytical reference standard with the molecular formula C6H16NO2S2Br and a molecular weight of 278.22 g/mol.
The molecular framework of [2-(Trimethylammonium)ethyl]methanethiosulfonate Bromide (C6H16NO2S2Br) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
