Chemical Structure
Description
4-iso-Octylphenol-di-ethoxylate (CAS 2315-61-9) is a high-purity analytical reference standard with the molecular formula C18H30O3 and a molecular weight of 294.43 g/mol.
The molecular framework of 4-iso-Octylphenol-di-ethoxylate (C18H30O3) is characterized by a steroid core, 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.
As a certified reference material (CRM), 4-iso-Octylphenol-di-ethoxylate 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.
