Chemical Structure
Description
The occurrence of 2,5,8,11,14,17,20,23,26,29,32,35-Dodecaoxaheptatriacontan-37-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-Dodecaoxaheptatriacontan-37-oic acid (CAS 1639205-66-5), molecular formula C25H50O14 and molecular weight 574.66 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,5,8,11,14,17,20,23,26,29,32,35-Dodecaoxaheptatriacontan-37-oic acid (C25H50O14) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
