5-(4-Chlorophenyl)-4H-1,2,4-triazole-3-carbaldehyde CAS 26899-27-4

Description

The occurrence of 5-(4-Chlorophenyl)-4H-1,2,4-triazole-3-carbaldehyde 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.

5-(4-Chlorophenyl)-4H-1,2,4-triazole-3-carbaldehyde (CAS 26899-27-4) is a high-purity analytical reference standard with the molecular formula C9H6ClN3O and a molecular weight of 207.62 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-(4-Chlorophenyl)-4H-1,2,4-triazole-3-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.62 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.
