Chemical Structure

4-Chloro-1-methyl-1h-imidazole-5-carbaldehyde CAS 193804-98-7 chemical structure

Description

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-Chloro-1-methyl-1h-imidazole-5-carbaldehyde is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

4-Chloro-1-methyl-1h-imidazole-5-carbaldehyde (CAS 193804-98-7) is a high-purity analytical reference standard with the molecular formula C5H5ClN2O and a molecular weight of 144.56 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
