Chemical Structure
Description
The occurrence of (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl phenyl mesitylphosphonate is closely related to a steroid core, a phosphonate group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl phenyl mesitylphosphonate (CAS 1463876-59-6), a certified reference material (molecular formula C25H35O3P, MW 414.52 g/mol) for analytical method development and quality control.
The molecular framework of (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl phenyl mesitylphosphonate (C25H35O3P) is characterized by a steroid core, a phosphonate group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), (Rp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl phenyl mesitylphosphonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
