Tri-tert-butyl 2,2',2''-(10-(2-(but-3-yn-1-ylamino)-2-oxoethyl)-1,4,7,10-tetraazacyclododecane-1,4,7-triyl)triacetate CAS 2125661-54-1 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Tri-tert-butyl 2,2',2''-(10-(2-(but-3-yn-1-ylamino)-2-oxoethyl)-1,4,7,10-tetraazacyclododecane-1,4,7-triyl)triacetate (CAS 2125661-54-1) is a high-purity analytical reference standard with the molecular formula C32H57N5O7 and a molecular weight of 623.82 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Tri-tert-butyl 2,2',2''-(10-(2-(but-3-yn-1-ylamino)-2-oxoethyl)-1,4,7,10-tetraazacyclododecane-1,4,7-triyl)triacetate is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 623.82 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).

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.
