Chemical Structure
Description
1,3-Dimethyl-1H-imidazol-3-ium methyl sulfate (CAS 97345-90-9) is a high-purity analytical reference standard with the molecular formula CH3O4SC5H9N2 and a molecular weight of 208.23 g/mol.
The molecular framework of 1,3-Dimethyl-1H-imidazol-3-ium methyl sulfate (CH3O4SC5H9N2) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,3-Dimethyl-1H-imidazol-3-ium methyl sulfate 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.
