Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 530.49 g/mol gives Clofazimine Impurity 4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Clofazimine Impurity 4 (CAS 78182-93-1), molecular formula C30H29Cl2N5 and molecular weight 530.49 g/mol, is a CATO reference standard with documented purity and traceability.
Clofazimine Impurity 4 (C30H29Cl2N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
