Chemical Structure
Description
As a certified reference material (CRM), (Methylsulfonyl)alanine 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.
(Methylsulfonyl)alanine (CAS 88547-35-7), molecular formula C4H9NO4S and molecular weight 167.18 g/mol, is a CATO reference standard with documented purity and traceability.
(Methylsulfonyl)alanine (C4H9NO4S) contains a carbohydrate-derived structure, an amide group, a sulfone group. It is notably hygroscopic, 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.
