Chemical Structure

4-(1-ethyl-1H-imidazol-4-yl)phenol CAS 74730-85-1 chemical structure

Description

4-(1-ethyl-1H-imidazol-4-yl)phenol (CAS 74730-85-1), molecular formula C11H12N2O and molecular weight 188.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-(1-ethyl-1H-imidazol-4-yl)phenol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 188.23 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).

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 manufactures 4-(1-ethyl-1H-imidazol-4-yl)phenol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
