Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 63.14 g/mol gives Ethanethiol-SD distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethanethiol-SD (CAS 33458-36-5), molecular formula C2H5DS and molecular weight 63.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, sulfur-containing functionality, Ethanethiol-SD is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 63.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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), Ethanethiol-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.
