Chemical Structure

Piracetam Impurity N2 CAS 925-57-5 chemical structure

Description

The occurrence of Piracetam Impurity N2 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Piracetam Impurity N2 (CAS 925-57-5) is a certified pharmaceutical impurity reference standard with the molecular formula C5H10O3 and a molecular weight of 118.13 g/mol.

Structurally, Piracetam Impurity N2 (C5H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 118.13 g/mol, it falls into the low-molecular-weight range.

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 N2 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.
