Compared with other compounds in its class, the molecular weight of 211.28 g/mol gives H-D-Cys(Bzl)-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies H-D-Cys(Bzl)-OH (CAS 23032-53-3), a certified reference material (molecular formula C10H13NO2S, MW 211.28 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, H-D-Cys(Bzl)-OH is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 211.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), H-D-Cys(Bzl)-OH 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.
