Description
CATO supplies Tetrakis(octadecylthio) Tetrathiafulvalene (CAS 105782-53-4), a certified reference material (molecular formula C78H148S8, MW 1342.53 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, an aromatic ring system, Tetrakis(octadecylthio) Tetrathiafulvalene is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1342.53 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), Tetrakis(octadecylthio) Tetrathiafulvalene 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.
