Chemical Structure

4-Octadecyloxybenzaldehyde CAS 4105-95-7 chemical structure

Description

4-Octadecyloxybenzaldehyde (CAS 4105-95-7), molecular formula C25H42O2 and molecular weight 374.60 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C25H42O2, 4-Octadecyloxybenzaldehyde contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 374.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
