N-(2-((3-(2-Chlorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)oxy)ethyl)propionamide CAS 1040663-44-2 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 N-(2-((3-(2-Chlorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)oxy)ethyl)propionamide.

CATO supplies N-(2-((3-(2-Chlorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)oxy)ethyl)propionamide (CAS 1040663-44-2), a certified reference material (molecular formula C16H16ClN5O2, MW 345.78 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N-(2-((3-(2-Chlorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)oxy)ethyl)propionamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 345.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), N-(2-((3-(2-Chlorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)oxy)ethyl)propionamide 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.
