Chemical Structure

Lansoprazole Impurity 9 CAS 37699-43-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Lansoprazole Impurity 9.

As a process- or degradation-related impurity, Lansoprazole Impurity 9 (CAS 37699-43-7, C7H8N2O3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Lansoprazole Impurity 9 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 168.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Lansoprazole Impurity 9 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.
