Chemical Structure

Ropinirole Impurity 24 CAS 1027600-42-5 chemical structure

Description

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

As a process- or degradation-related impurity, Ropinirole Impurity 24 (CAS 1027600-42-5, C17H26N2O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Ropinirole Impurity 24 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 290.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Ropinirole Impurity 24 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.
