Olodaterol Impurity 1 CAS 78-09-1 chemical structure

Description

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

Olodaterol Impurity 1 (CAS 78-09-1) is a certified pharmaceutical impurity reference standard with the molecular formula C9H20O4 and a molecular weight of 192.25 g/mol.

The molecular framework of Olodaterol Impurity 1 (C9H20O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

As a certified reference material (CRM), Olodaterol Impurity 1 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.
