Chemical Structure

3-Butyl-1-methyl-1H-imidazol-3-ium hydroxide CAS 528818-81-7 chemical structure

Description

The molecular framework of 3-Butyl-1-methyl-1H-imidazol-3-ium hydroxide (C8H15N2HO) is characterized by an amide 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.

3-Butyl-1-methyl-1H-imidazol-3-ium hydroxide (CAS 528818-81-7), molecular formula C8H15N2HO and molecular weight 156.23 g/mol, is a CATO reference standard with documented purity and traceability.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
