Description
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.
62669-66-3 9-(2-Carboxyphenyl)-3,6-bis(ethylamino)-2,7-dimethylxanthylium perchlorate Xanthylium, 9-(2-carboxyphenyl)-3,6-bis(ethylamino)-2,7-dimethyl-, perchlorate (1:1) Xanthylium, 9-(2-carboxyphenyl)-3,6-bis(ethylamino)-2,7-dimethyl-, perchlorate EINECS 263-686-2 (CAS 62669-66-3), molecular formula C26H38N2O3HClO4 and molecular weight 527.06 g/mol, is a CATO reference standard with documented purity and traceability.
62669-66-3 9-(2-Carboxyphenyl)-3,6-bis(ethylamino)-2,7-dimethylxanthylium perchlorate Xanthylium, 9-(2-carboxyphenyl)-3,6-bis(ethylamino)-2,7-dimethyl-, perchlorate (1:1) Xanthylium, 9-(2-carboxyphenyl)-3,6-bis(ethylamino)-2,7-dimethyl-, perchlorate EINECS 263-686-2 (C26H38N2O3HClO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
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.
