6-Chloro-3-(4-methoxyphenyl)-[1,2,4]triazolo[3,4-a]phthalazine CAS 98123-77-4

Description

The occurrence of 6-Chloro-3-(4-methoxyphenyl)-[1,2,4]triazolo[3,4-a]phthalazine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Chloro-3-(4-methoxyphenyl)-[1,2,4]triazolo[3,4-a]phthalazine (CAS 98123-77-4), molecular formula C16H11ClN4O and molecular weight 310.74 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 6-Chloro-3-(4-methoxyphenyl)-[1,2,4]triazolo[3,4-a]phthalazine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 310.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
