Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 7-Chloro-6-Fluoro-1-Ethyl-1,4-Dihydro-4-Oxopyrido(2,3-c)Pyridazine-3-Carboxylic Acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 7-Chloro-6-Fluoro-1-Ethyl-1,4-Dihydro-4-Oxopyrido(2,3-c)Pyridazine-3-Carboxylic Acid (CAS 120876-49-5), a certified reference material (molecular formula C10H7ClFN3O3, MW 271.63 g/mol) for analytical method development and quality control.
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.
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.
