Chemical Structure
Description
As a certified reference material (CRM), (Sp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (2,5-dihydroxyphenyl)(4-vinylbenzyl)phosphinate 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.
(Sp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (2,5-dihydroxyphenyl)(4-vinylbenzyl)phosphinate (CAS 1420992-16-0) is a high-purity analytical reference standard with the molecular formula C25H33O4P and a molecular weight of 428.50 g/mol.
The molecular framework of (Sp)-(1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl (2,5-dihydroxyphenyl)(4-vinylbenzyl)phosphinate (C25H33O4P) is characterized by a flavonoid core, a phosphate ester 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
