Chemical Structure
Description
As a certified reference material (CRM), 7,8,9,10-Tetrahydro-3-hydroxy-4-methyl-6H-dibenzo[b,d]pyran-6-one 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.
7,8,9,10-Tetrahydro-3-hydroxy-4-methyl-6H-dibenzo[b,d]pyran-6-one (CAS 55047-37-5), molecular formula C14H14O3 and molecular weight 230.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 7,8,9,10-Tetrahydro-3-hydroxy-4-methyl-6H-dibenzo[b,d]pyran-6-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 230.26 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.
