Chemical Structure

Tri-tert-butyl 1,4,7,10-Tetraazacyclododecane-1,4,7-triacetate Hydrobromide CAS 149353-23-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tri-tert-butyl 1,4,7,10-Tetraazacyclododecane-1,4,7-triacetate Hydrobromide.

Tri-tert-butyl 1,4,7,10-Tetraazacyclododecane-1,4,7-triacetate Hydrobromide (CAS 149353-23-1) is a high-purity analytical reference standard with the molecular formula C26H50N4O6HBr and a molecular weight of 595.62 g/mol.

Structurally, Tri-tert-butyl 1,4,7,10-Tetraazacyclododecane-1,4,7-triacetate Hydrobromide (C26H50N4O6HBr) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 595.62 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), Tri-tert-butyl 1,4,7,10-Tetraazacyclododecane-1,4,7-triacetate Hydrobromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
