Chemical Structure

[5-(2-Chloro-phenyl)-tetrazol-2-yl]-acetic acid CAS 5626-38-0 chemical structure

Description

The occurrence of [5-(2-Chloro-phenyl)-tetrazol-2-yl]-acetic acid 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-(2-Chloro-phenyl)-tetrazol-2-yl]-acetic acid (CAS 5626-38-0) is a high-purity analytical reference standard with the molecular formula C9H7ClN4O2 and a molecular weight of 238.63 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, [5-(2-Chloro-phenyl)-tetrazol-2-yl]-acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.63 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.

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.
