Omeprazole Impurity 44 CAS 69818-23-1

Description

Compared with other compounds in its class, the molecular weight of 138.12 g/mol gives Omeprazole Impurity 44 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Omeprazole Impurity 44 (CAS 69818-23-1) is a certified pharmaceutical impurity reference standard with the molecular formula C7H6O3 and a molecular weight of 138.12 g/mol.

Structurally, Omeprazole Impurity 44 (C7H6O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 138.12 g/mol, it falls into the low-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), Omeprazole Impurity 44 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.
