Chemical Structure

3-Ethyl-1-methyl-1H-imidazol-3-ium hexafluorostibate(V) CAS 305370-81-4 chemical structure

Description

As a certified reference material (CRM), 3-Ethyl-1-methyl-1H-imidazol-3-ium hexafluorostibate(V) 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.

3-Ethyl-1-methyl-1H-imidazol-3-ium hexafluorostibate(V) (CAS 305370-81-4) is a high-purity analytical reference standard with the molecular formula F6SbC6H11N2 and a molecular weight of 346.92 g/mol.

The molecular framework of 3-Ethyl-1-methyl-1H-imidazol-3-ium hexafluorostibate(V) (F6SbC6H11N2) is characterized by fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
