Carboprost Impurity 4 CAS 62776-96-9 chemical structure

Description

As a certified reference material (CRM), Carboprost Impurity 4 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.

Carboprost Impurity 4 (CAS 62776-96-9) is a certified pharmaceutical impurity reference standard with the molecular formula C22H38O5 and a molecular weight of 382.53 g/mol.

Carboprost Impurity 4 (C22H38O5) contains a steroid core, 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 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.
