Chemical Structure

Glipizide EP Impurity B CAS 108-91-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 99.17 g/mol gives Glipizide EP Impurity B distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Glipizide EP Impurity B (CAS 108-91-8) is a certified pharmaceutical impurity reference standard with the molecular formula C6H13N and a molecular weight of 99.17 g/mol.

The molecular framework of Glipizide EP Impurity B (C6H13N) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), Glipizide EP Impurity B 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.
