Chemical Structure
Description
The occurrence of 5-(2-Bromoethyl)-1H-tetrazole is closely related to a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(2-Bromoethyl)-1H-tetrazole (CAS 82049-79-4) is a high-purity analytical reference standard with the molecular formula C3H5BrN4 and a molecular weight of 177.00 g/mol.
Based on its molecular formula C3H5BrN4, 5-(2-Bromoethyl)-1H-tetrazole contains a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 177.00 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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.
CATO manufactures 5-(2-Bromoethyl)-1H-tetrazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
