Chemical Structure
Description
The occurrence of 2,5,8,11,14,17,20,23,26,29,32,35,38-Tridecaoxahentetracontan-41-oic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,5,8,11,14,17,20,23,26,29,32,35,38-Tridecaoxahentetracontan-41-oic acid (CAS 2170098-33-4), molecular formula C28H56O15 and molecular weight 632.74 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C28H56O15, 2,5,8,11,14,17,20,23,26,29,32,35,38-Tridecaoxahentetracontan-41-oic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 632.74 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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.
