Chemical Structure

Cimetidine EP Impurity I CAS 38585-62-5 chemical structure

Description

Cimetidine EP Impurity I (CAS 38585-62-5) is a certified pharmaceutical impurity reference standard with the molecular formula C5H8N2OHCl and a molecular weight of 148.59 g/mol.

The molecular framework of Cimetidine EP Impurity I (C5H8N2OHCl) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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), Cimetidine EP Impurity I 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.
