Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4,5-Dihydro-1H-imidazol-2-yl)-3-ethyl-1,2,3,4-tetrahydroquinoline.
1-(4,5-Dihydro-1H-imidazol-2-yl)-3-ethyl-1,2,3,4-tetrahydroquinoline (CAS 736893-14-4) is a high-purity analytical reference standard with the molecular formula C14H19N3 and a molecular weight of 229.32 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-(4,5-Dihydro-1H-imidazol-2-yl)-3-ethyl-1,2,3,4-tetrahydroquinoline is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 229.32 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(4,5-Dihydro-1H-imidazol-2-yl)-3-ethyl-1,2,3,4-tetrahydroquinoline 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.
