Description
1-Octadecane-d37-thiol (CAS 668433-57-6), molecular formula C18HD37S and molecular weight 323.79 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, sulfur-containing functionality, a polycyclic aromatic system, 1-Octadecane-d37-thiol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.79 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.
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), 1-Octadecane-d37-thiol 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.
