Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2,3,8-Trihydroxy-4-isopropyl-6-methyl-1-naphthaldehyde (CAS 40817-07-0), a certified reference material (molecular formula C15H16O4, MW 260.29 g/mol) for analytical method development and quality control.
Structurally, 2,3,8-Trihydroxy-4-isopropyl-6-methyl-1-naphthaldehyde (C15H16O4) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 260.29 g/mol, it falls into the medium-molecular-weight range. 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).
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.
