Chemical Structure
Description
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.
Dicyclohexyl(4-methoxy-3-(2,4,6-trimethoxyphenyl)naphthalen-2-yl)phosphine (CAS 1332745-81-9), molecular formula C32H41O4P and molecular weight 520.64 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Dicyclohexyl(4-methoxy-3-(2,4,6-trimethoxyphenyl)naphthalen-2-yl)phosphine (C32H41O4P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
As a certified reference material (CRM), Dicyclohexyl(4-methoxy-3-(2,4,6-trimethoxyphenyl)naphthalen-2-yl)phosphine 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.
