Chemical Structure

1-(1H-Benzo[d][1,2,3]triazol-1-yl)-5-chloropentan-2-one CAS 305851-08-5 chemical structure

Description

The occurrence of 1-(1H-Benzo[d][1,2,3]triazol-1-yl)-5-chloropentan-2-one 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.

1-(1H-Benzo[d][1,2,3]triazol-1-yl)-5-chloropentan-2-one (CAS 305851-08-5) is a high-purity analytical reference standard with the molecular formula C11H12ClN3O and a molecular weight of 237.69 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(1H-Benzo[d][1,2,3]triazol-1-yl)-5-chloropentan-2-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 237.69 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 1-(1H-Benzo[d][1,2,3]triazol-1-yl)-5-chloropentan-2-one 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.
