Chemical Structure

Piracetam impurity 41 CAS 87148-72-9 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 Piracetam impurity 41.

Piracetam impurity 41 (CAS 87148-72-9) is a certified pharmaceutical impurity reference standard with the molecular formula C8H13NO3 and a molecular weight of 171.19 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Piracetam impurity 41 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 171.19 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), Piracetam impurity 41 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.
