Chemical Structure

4-Aminopyridin-3-ol dihydrochloride CAS 1081776-23-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 146.57 g/mol gives 4-Aminopyridin-3-ol dihydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Aminopyridin-3-ol dihydrochloride (CAS 1081776-23-9), molecular formula C5H6N2OHCl and molecular weight 146.57 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Aminopyridin-3-ol dihydrochloride (C5H6N2OHCl) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4-Aminopyridin-3-ol dihydrochloride 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.
