6-(tert-Butyl)-2H-chromene CAS 156545-32-3 chemical structure

Description

CATO supplies 6-(tert-Butyl)-2H-chromene (CAS 156545-32-3), a certified reference material (molecular formula C13H16O, MW 188.27 g/mol) for analytical method development and quality control.

6-(tert-Butyl)-2H-chromene (C13H16O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
