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 (3-nitrophenyl) benzylphosphonate.
CATO supplies (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (3-nitrophenyl) benzylphosphonate (CAS 1463876-84-7), a certified reference material (molecular formula C23H30NO5P, MW 431.46 g/mol) for analytical method development and quality control.
Based on its molecular formula C23H30NO5P, (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (3-nitrophenyl) benzylphosphonate contains a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 431.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
