Isoprenaline Impurity 7 CAS CATO-C4X-27757 chemical structure

Description

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

Isoprenaline Impurity 7 (CAS CATO-C4X-27757) is a certified pharmaceutical impurity reference standard with the molecular formula C19H21NO6 and a molecular weight of 359.37 g/mol.

Isoprenaline Impurity 7 (C19H21NO6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Isoprenaline Impurity 7 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.
