Ipratropium Impurity 24 (Mixture of Isomers) CAS 17812-46-3

Description

The occurrence of Ipratropium Impurity 24 (Mixture of Isomers) is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ipratropium Impurity 24 (Mixture of Isomers) (CAS 17812-46-3) is a certified pharmaceutical impurity reference standard with the molecular formula C20H28NO2Br and a molecular weight of 394.35 g/mol.

Structurally, Ipratropium Impurity 24 (Mixture of Isomers) (C20H28NO2Br) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 394.35 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Ipratropium Impurity 24 (Mixture of Isomers) 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.
