Chemical Structure
Description
5'-(2-Formylphenyl)-[1,1':3',1''-terphenyl]-2,2''-dicarbaldehyde (C27H18O3) contains a steroid core, a hydroxyl group, an ether linkage. 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.
5'-(2-Formylphenyl)-[1,1':3',1''-terphenyl]-2,2''-dicarbaldehyde (CAS 87226-90-2), molecular formula C27H18O3 and molecular weight 390.43 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
