Chemical Structure

1-(2-Chloroethyl)-1H-1,2,3,4-tetrazole CAS 15284-27-2 chemical structure

Description

As a certified reference material (CRM), 1-(2-Chloroethyl)-1H-1,2,3,4-tetrazole 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.

1-(2-Chloroethyl)-1H-1,2,3,4-tetrazole (CAS 15284-27-2) is a high-purity analytical reference standard with the molecular formula C3H5ClN4 and a molecular weight of 132.55 g/mol.

Owing to a nitrile group, chlorine substitution, 1-(2-Chloroethyl)-1H-1,2,3,4-tetrazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.55 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
