Indacaterol impurity 82 CAS 1403389-05-8

Description

Compared with other compounds in its class, the molecular weight of 394.51 g/mol gives Indacaterol impurity 82 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Indacaterol impurity 82 (CAS 1403389-05-8) is a certified pharmaceutical impurity reference standard with the molecular formula C24H30N2O3 and a molecular weight of 394.51 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Indacaterol impurity 82 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 394.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 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.

As a certified reference material (CRM), Indacaterol impurity 82 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.
