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.
5,7-Dimethylbenzofuran (CAS 64965-91-9) is a high-purity analytical reference standard with the molecular formula C10H10O and a molecular weight of 146.19 g/mol.
Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 5,7-Dimethylbenzofuran is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.19 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).
CATO manufactures 5,7-Dimethylbenzofuran 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.
