Chemical Structure

1,3-Di-tert-butyl-4,5-dihydro-1H-imidazol-3-ium tetrafluoroborate CAS 137581-21-6 chemical structure

Description

1,3-Di-tert-butyl-4,5-dihydro-1H-imidazol-3-ium tetrafluoroborate (CAS 137581-21-6), molecular formula C11H23N2BF4 and molecular weight 270.12 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H23N2BF4, 1,3-Di-tert-butyl-4,5-dihydro-1H-imidazol-3-ium tetrafluoroborate contains fluorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 270.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 1,3-Di-tert-butyl-4,5-dihydro-1H-imidazol-3-ium tetrafluoroborate 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.
