Description

(+)-(18-Crown-6)-2,3,11,12-tetracarboxamide 57207-22-4 [2R-(2R*,3R*,11R*,12R*)]-N,N,N',N',N'',N'',N''',N'''-Octamethyl-1,4,7,10,13,16-hexaoxacyclooctadecane-2,3,11,12-tetracarboxamide (CAS 57207-22-4), molecular formula C24H44N4O10 and molecular weight 548.63 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (+)-(18-Crown-6)-2,3,11,12-tetracarboxamide 57207-22-4 [2R-(2R*,3R*,11R*,12R*)]-N,N,N',N',N'',N'',N''',N'''-Octamethyl-1,4,7,10,13,16-hexaoxacyclooctadecane-2,3,11,12-tetracarboxamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 548.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
