Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 221.69 g/mol gives 5-N-phenylpyridine-2,5-diamine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-N-phenylpyridine-2,5-diamine hydrochloride (CAS 1955524-40-9), molecular formula C11H11N3HCl and molecular weight 221.69 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 5-N-phenylpyridine-2,5-diamine hydrochloride is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 221.69 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
