Chemical Structure
Description
As a certified reference material (CRM), 5-(1-chloroethyl)-1-methyl-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.
5-(1-chloroethyl)-1-methyl-1H-1,2,3,4-tetrazole (CAS 186958-71-4) is a high-purity analytical reference standard with the molecular formula C4H7ClN4 and a molecular weight of 146.58 g/mol.
5-(1-chloroethyl)-1-methyl-1H-1,2,3,4-tetrazole (C4H7ClN4) 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.
