2-(Methylamino)-4h,5h,6h-cyclopenta[b]thiophene-3-carbonitrile CAS 1342394-71-1

Description

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.

2-(Methylamino)-4h,5h,6h-cyclopenta[b]thiophene-3-carbonitrile (CAS 1342394-71-1), molecular formula C9H10N2S and molecular weight 178.25 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(Methylamino)-4h,5h,6h-cyclopenta[b]thiophene-3-carbonitrile (C9H10N2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

As a certified reference material (CRM), 2-(Methylamino)-4h,5h,6h-cyclopenta[b]thiophene-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.
