Chemical Structure
Description
Dibenzo[b,d]thiophen-3-ol (CAS 69747-77-9), molecular formula C12H8OS and molecular weight 200.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, Dibenzo[b,d]thiophen-3-ol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 200.26 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.
CATO manufactures Dibenzo[b,d]thiophen-3-ol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
