Chemical Structure

4-Ethoxyquinoline CAS 13720-91-7 chemical structure

Description

As a certified reference material (CRM), 4-Ethoxyquinoline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

4-Ethoxyquinoline (CAS 13720-91-7) is a high-purity analytical reference standard with the molecular formula C11H11NO and a molecular weight of 173.21 g/mol.

Structurally, 4-Ethoxyquinoline (C11H11NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 173.21 g/mol, it falls into the medium-molecular-weight range. 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).

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