Chemical Structure
Description
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.
1,3-Bis((R)-1-phenylethyl)-1H-imidazol-3-ium chloride (CAS 186354-46-1) is a high-purity analytical reference standard with the molecular formula C19H23N2Cl and a molecular weight of 314.86 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 1,3-Bis((R)-1-phenylethyl)-1H-imidazol-3-ium chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 1,3-Bis((R)-1-phenylethyl)-1H-imidazol-3-ium chloride 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.
