Chemical Structure
Description
Owing to a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage, 4-Hydroxyphenyl ((1R,2S,5R)-2-isopropyl-5-methylcyclohexyl) phenylphosphonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 388.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 4-Hydroxyphenyl ((1R,2S,5R)-2-isopropyl-5-methylcyclohexyl) phenylphosphonate (CAS 1420991-94-1), a certified reference material (molecular formula C22H29O4P, MW 388.44 g/mol) for analytical method development and quality control.
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.
