Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 3-hydroxy-7,8-dihydropyrido[4,3-c]pyridazine-6(5H)-carboxylate.
CATO supplies Ethyl 3-hydroxy-7,8-dihydropyrido[4,3-c]pyridazine-6(5H)-carboxylate (CAS 39716-48-8), a certified reference material (molecular formula C10H13N3O3, MW 223.23 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 3-hydroxy-7,8-dihydropyrido[4,3-c]pyridazine-6(5H)-carboxylate (C10H13N3O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Ethyl 3-hydroxy-7,8-dihydropyrido[4,3-c]pyridazine-6(5H)-carboxylate 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.
