Description
CATO supplies N-Acetyl-S-(1,1-Dibromo-2,2-Difluoroethyl)-1-Cysteine (CAS 119018-03-0), a certified reference material (molecular formula C7H9Br2F2NO3S, MW 385.02 g/mol) for analytical method development and quality control.
N-Acetyl-S-(1,1-Dibromo-2,2-Difluoroethyl)-1-Cysteine (C7H9Br2F2NO3S) 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.
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.
As a certified reference material (CRM), N-Acetyl-S-(1,1-Dibromo-2,2-Difluoroethyl)-1-Cysteine 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.
