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 3,5-Dibromo-4-((6-oxo-1,6-dihydropyridazin-3-yl)oxy)phenethyl acetate.
3,5-Dibromo-4-((6-oxo-1,6-dihydropyridazin-3-yl)oxy)phenethyl acetate (CAS 920509-41-7), molecular formula C14H12Br2N2O4 and molecular weight 432.06 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,5-Dibromo-4-((6-oxo-1,6-dihydropyridazin-3-yl)oxy)phenethyl acetate (C14H12Br2N2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
