Description

2,2',2'',2''',2'''',2'''''-((15,35,55,75,95,115-Hexa-tert-butyl-1,3,5,7,9,11(1,3)-hexabenzenacyclododecaphane-12,32,52,72,92,112-hexayl)hexakis(oxy))hexaacetic acid (C78H96O18) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 2,2',2'',2''',2'''',2'''''-((15,35,55,75,95,115-Hexa-tert-butyl-1,3,5,7,9,11(1,3)-hexabenzenacyclododecaphane-12,32,52,72,92,112-hexayl)hexakis(oxy))hexaacetic acid (CAS 123795-01-7), a certified reference material (molecular formula C78H96O18, MW 1321.59 g/mol) for analytical method development and quality control.

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.
