Compared with other compounds in its class, the molecular weight of 396.56 g/mol gives 4-n-Nonylphenol tetraethoxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-n-Nonylphenol tetraethoxylate (CAS 7311-27-5), molecular formula C23H40O5 and molecular weight 396.56 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, 4-n-Nonylphenol tetraethoxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 396.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-n-Nonylphenol tetraethoxylate 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.
