Description
CATO supplies 6,7,8,9-Tetrahydro-5H-benzo[7]annulene-2-carbaldehyde (CAS 65898-51-3), a certified reference material (molecular formula C12H14O, MW 174.24 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 6,7,8,9-Tetrahydro-5H-benzo[7]annulene-2-carbaldehyde is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 174.24 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
