Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-(Ethylthio)-3-methoxy-2-phenylimidazo[1,2-b]pyridazine (CAS 113121-35-0) is a high-purity analytical reference standard with the molecular formula C15H15N3OS and a molecular weight of 285.36 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 6-(Ethylthio)-3-methoxy-2-phenylimidazo[1,2-b]pyridazine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.36 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).
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.
