2-Amino-4,5-dimethyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile CAS 1343356-34-2 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 2-Amino-4,5-dimethyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile.

2-Amino-4,5-dimethyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile (CAS 1343356-34-2), molecular formula C11H14N2S and molecular weight 206.31 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Amino-4,5-dimethyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile (C11H14N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 206.31 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).

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.

As a certified reference material (CRM), 2-Amino-4,5-dimethyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile 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.
