(Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (4-(trifluoromethyl)phenyl) phenylphosphonate CAS 1463876-01-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (4-(trifluoromethyl)phenyl) phenylphosphonate.

(Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (4-(trifluoromethyl)phenyl) phenylphosphonate (CAS 1463876-01-8) is a high-purity analytical reference standard with the molecular formula C23H28F3O3P and a molecular weight of 440.44 g/mol.

Structurally, (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (4-(trifluoromethyl)phenyl) phenylphosphonate (C23H28F3O3P) contains a steroid core, a phosphonate group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 440.44 g/mol, it falls into the moderately-high-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.

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.
