Chemical Structure

3-Aminoisonicotinohydrazide CAS 64189-08-8 chemical structure

Description

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

3-Aminoisonicotinohydrazide (CAS 64189-08-8), molecular formula C6H8N4O and molecular weight 152.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Aminoisonicotinohydrazide (C6H8N4O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), 3-Aminoisonicotinohydrazide 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.
