Chemical Structure
Description
Methyl mercaptan-Sd (CAS 16978-68-0), molecular formula CH3DS and molecular weight 49.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl mercaptan-Sd (CH3DS) is characterized by deuterium isotope labeling, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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), Methyl mercaptan-Sd 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.
