Chemical Structure

Ethyl 2-(1H-tetrazol-1-yl)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate CAS 692275-81-3 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 Ethyl 2-(1H-tetrazol-1-yl)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate.

Ethyl 2-(1H-tetrazol-1-yl)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate (CAS 692275-81-3) is a high-purity analytical reference standard with the molecular formula C12H14N4O2S and a molecular weight of 278.33 g/mol.

Structurally, Ethyl 2-(1H-tetrazol-1-yl)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate (C12H14N4O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 278.33 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).
