Chemical Structure
Description
As a certified reference material (CRM), [1-(Trimethylammonium)methyl] 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.
CATO supplies [1-(Trimethylammonium)methyl] Methanethiosulfonate Bromide (CAS 386229-81-8), a certified reference material (molecular formula C5H14NO2S2Br, MW 264.20 g/mol) for analytical method development and quality control.
Structurally, [1-(Trimethylammonium)methyl] Methanethiosulfonate Bromide (C5H14NO2S2Br) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 264.20 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
