Description

Compared with other compounds in its class, the molecular weight of 464.62 g/mol gives Bis((1r,2s,5r)-2-isopropyl-5-methylcyclohexyl) ((s)-hydroxy(phenyl)methyl)phosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Bis((1r,2s,5r)-2-isopropyl-5-methylcyclohexyl) ((s)-hydroxy(phenyl)methyl)phosphonate (CAS 889103-61-1), a certified reference material (molecular formula C27H45O4P, MW 464.62 g/mol) for analytical method development and quality control.

Structurally, Bis((1r,2s,5r)-2-isopropyl-5-methylcyclohexyl) ((s)-hydroxy(phenyl)methyl)phosphonate (C27H45O4P) contains a steroid core, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 464.62 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.
