Chemical Structure
Description
Structurally, (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl benzyl(2-hydroxyphenyl)phosphinate (C23H31O3P) contains a steroid core, a phosphonate group, a hydroxyl group, an ether linkage. 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 386.46 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl benzyl(2-hydroxyphenyl)phosphinate (CAS 1464049-31-7), a certified reference material (molecular formula C23H31O3P, MW 386.46 g/mol) for analytical method development and quality control.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
