Description
CATO supplies 2-(5,6,7,8-Tetrahydronaphthalen-1-yl)acetic acid (CAS 776-50-1), a certified reference material (molecular formula C17H20O2, MW 256.34 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, 2-(5,6,7,8-Tetrahydronaphthalen-1-yl)acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.34 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.
