2-Methyldibenzothiophene CAS 20928-02-3 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2-Methyldibenzothiophene (CAS 20928-02-3) is a high-purity analytical reference standard with the molecular formula C13H10S and a molecular weight of 198.28 g/mol.

Owing to sulfur-containing functionality, an aromatic ring system, 2-Methyldibenzothiophene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 198.28 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.

As a certified reference material (CRM), 2-Methyldibenzothiophene 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.
