Chemical Structure

Proguanil EP Impurity G CAS 807308-41-4 chemical structure

Description

The occurrence of Proguanil EP Impurity G is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Proguanil EP Impurity G (CAS 807308-41-4) is a certified pharmaceutical impurity reference standard with the molecular formula C11H16ClN5 and a molecular weight of 253.73 g/mol.

Based on its molecular formula C11H16ClN5, Proguanil EP Impurity G contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 253.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Proguanil EP Impurity G under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
