Chemical Structure

Atracurium Impurity 71 CAS 5436-53-3 chemical structure

Description

As a certified reference material (CRM), Atracurium Impurity 71 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.

Atracurium Impurity 71 (CAS 5436-53-3) is a high-purity analytical reference standard with the molecular formula C6H13N3O2 and a molecular weight of 159.19 g/mol.

The molecular framework of Atracurium Impurity 71 (C6H13N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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