Chemical Structure
Description
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.
CATO supplies 2-Hydroxy-3-methyl-7,8,9,10-tetrahydro-6H-benzo[c]chromen-6-one (CAS 710991-30-3), a certified reference material (molecular formula C14H14O3, MW 230.26 g/mol) for analytical method development and quality control.
Structurally, 2-Hydroxy-3-methyl-7,8,9,10-tetrahydro-6H-benzo[c]chromen-6-one (C14H14O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 230.26 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
