99590-86-0 Egta acetoxymethyl ester 6,9-Dioxa-3,12-diazatetradecanedioic acid, 3,12-bis(2-((acetyloxy)methoxy)-2-oxoethyl)-, bis((acetyloxy)methyl) ester Egta-am Egta-AME CAS 99590-86-0

Description

Structurally, 99590-86-0 Egta acetoxymethyl ester 6,9-Dioxa-3,12-diazatetradecanedioic acid, 3,12-bis(2-((acetyloxy)methoxy)-2-oxoethyl)-, bis((acetyloxy)methyl) ester Egta-am Egta-AME (C26H40N2O18) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 668.60 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

99590-86-0 Egta acetoxymethyl ester 6,9-Dioxa-3,12-diazatetradecanedioic acid, 3,12-bis(2-((acetyloxy)methoxy)-2-oxoethyl)-, bis((acetyloxy)methyl) ester Egta-am Egta-AME (CAS 99590-86-0), molecular formula C26H40N2O18 and molecular weight 668.60 g/mol, is a CATO reference standard with documented purity and traceability.

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.
