Chemical Structure

Minoxidil EP Impurity E CAS 24867-26-3 chemical structure

Description

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

Minoxidil EP Impurity E (CAS 24867-26-3) is a certified pharmaceutical impurity reference standard with the molecular formula C9H15N5 and a molecular weight of 193.25 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Minoxidil EP Impurity E is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 193.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Minoxidil EP Impurity E 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.
