Chemical Structure
Description
1-[4-(chloromethyl)-3-methylphenyl]-1H-imidazole hydrochloride (CAS 1803585-47-8), molecular formula C11H11ClN2HCl and molecular weight 243.13 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 1-[4-(chloromethyl)-3-methylphenyl]-1H-imidazole hydrochloride is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 243.13 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.
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.
