5-Bromo-2-(tert-butyl)-2H-tetrazole CAS 2228325-18-4

Description

The occurrence of 5-Bromo-2-(tert-butyl)-2H-tetrazole is closely related to a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Bromo-2-(tert-butyl)-2H-tetrazole (CAS 2228325-18-4) is a high-purity analytical reference standard with the molecular formula C5H9BrN4 and a molecular weight of 205.06 g/mol.

Owing to a nitrile group, bromine substitution, 5-Bromo-2-(tert-butyl)-2H-tetrazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 205.06 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).

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.

As a certified reference material (CRM), 5-Bromo-2-(tert-butyl)-2H-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.
