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.
CATO supplies 4,4'-[[2-[[3-(4-Carboxyphenoxy)-2,2-bis[(4-carboxyphenoxy)methyl]propoxy]methyl]-2-[(4-carboxyphenoxy)methyl]-1,3-propanediyl]bis(oxy)]bis[benzoic acid] (CAS 1359740-26-3), a certified reference material (molecular formula C52H46O19, MW 974.91 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 4,4'-[[2-[[3-(4-Carboxyphenoxy)-2,2-bis[(4-carboxyphenoxy)methyl]propoxy]methyl]-2-[(4-carboxyphenoxy)methyl]-1,3-propanediyl]bis(oxy)]bis[benzoic acid] is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 974.91 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
