Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 118.53 g/mol gives 5-(Chloromethyl)tetrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-(Chloromethyl)tetrazole (CAS 55408-11-2) is a high-purity analytical reference standard with the molecular formula C2H3ClN4 and a molecular weight of 118.53 g/mol.
5-(Chloromethyl)tetrazole (C2H3ClN4) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 5-(Chloromethyl)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.
