Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2,2',2'',2''',2'''',2''''',2'''''',2'''''''-((15,35,55,75,95,115,135,155-Octa-tert-butyl-1,3,5,7,9,11,13,15(1,3)-octabenzenacyclohexadecaphane-12,32,52,72,92,112,132,152-octayl)octakis(oxy))octaacetic acid is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1762.11 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).

CATO supplies 2,2',2'',2''',2'''',2''''',2'''''',2'''''''-((15,35,55,75,95,115,135,155-Octa-tert-butyl-1,3,5,7,9,11,13,15(1,3)-octabenzenacyclohexadecaphane-12,32,52,72,92,112,132,152-octayl)octakis(oxy))octaacetic acid (CAS 116851-59-3), a certified reference material (molecular formula C104H128O24, MW 1762.11 g/mol) for analytical method development and quality control.

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.
