Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2',5'-Bis((4-aminophenyl)ethynyl)-[1,1':4',1''-terphenyl]-4,4''-dicarbaldehyde (CAS 2375652-87-0), a certified reference material (molecular formula C36H24N2O2, MW 516.59 g/mol) for analytical method development and quality control.
2',5'-Bis((4-aminophenyl)ethynyl)-[1,1':4',1''-terphenyl]-4,4''-dicarbaldehyde (C36H24N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
