Description

Compared with other compounds in its class, the molecular weight of 598.85 g/mol gives 2',5'-Bis(decyloxy)-[1,1':4',1''-terphenyl]-4,4''-dicarbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2',5'-Bis(decyloxy)-[1,1':4',1''-terphenyl]-4,4''-dicarbaldehyde (CAS 850446-24-1), molecular formula C40H54O4 and molecular weight 598.85 g/mol, is a CATO reference standard with documented purity and traceability.

2',5'-Bis(decyloxy)-[1,1':4',1''-terphenyl]-4,4''-dicarbaldehyde (C40H54O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
