Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 181.21 g/mol gives DL-Methionine Sulfone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
DL-Methionine Sulfone (CAS 820-10-0), molecular formula C5H11NO4S and molecular weight 181.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of DL-Methionine Sulfone (C5H11NO4S) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), DL-Methionine Sulfone 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.
