Chemical Structure
Description
The occurrence of ((1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl)diphenylphosphane is closely related to organophosphorus functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies ((1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl)diphenylphosphane (CAS 43077-31-2), a certified reference material (molecular formula C22H29P, MW 324.44 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, a polycyclic aromatic system, ((1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl)diphenylphosphane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.44 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.
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.
