Chemical Structure

5-chloro-2-ethyl-1H-imidazole-4-carbaldehyde CAS 145824-12-0 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.

CATO supplies 5-chloro-2-ethyl-1H-imidazole-4-carbaldehyde (CAS 145824-12-0), a certified reference material (molecular formula C6H11ClN2O, MW 162.62 g/mol) for analytical method development and quality control.

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-chloro-2-ethyl-1H-imidazole-4-carbaldehyde is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.62 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.

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.
