5,8-Dioxa-2,11-diazatetradecanoic acid, 14-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)-12-oxo-, 1,1-dimethylethyl ester CAS 1801876-84-5

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.

CATO supplies 5,8-Dioxa-2,11-diazatetradecanoic acid, 14-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)-12-oxo-, 1,1-dimethylethyl ester (CAS 1801876-84-5), a certified reference material (molecular formula C18H29N3O7, MW 399.44 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5,8-Dioxa-2,11-diazatetradecanoic acid, 14-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)-12-oxo-, 1,1-dimethylethyl ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 399.44 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.
