Chemical Structure
Description
As a certified reference material (CRM), Dibenzothiophene 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.
CATO supplies Dibenzothiophene (CAS 132-65-0), a certified reference material (molecular formula C12H8S, MW 184.26 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, an aromatic ring system, Dibenzothiophene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 184.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
