Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including S-(1,2,2-Trichlorovinyl)-Cysteine.
CATO supplies S-(1,2,2-Trichlorovinyl)-Cysteine (CAS 98025-31-1), a certified reference material (molecular formula C5H6Cl3NO2S, MW 250.53 g/mol) for analytical method development and quality control.
S-(1,2,2-Trichlorovinyl)-Cysteine (C5H6Cl3NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
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), S-(1,2,2-Trichlorovinyl)-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.
