Chemical Structure

1-Methyl-3-(thiophen-3-yl)piperazine CAS 111781-52-3 chemical structure

Description

CATO supplies 1-Methyl-3-(thiophen-3-yl)piperazine (CAS 111781-52-3), a certified reference material (molecular formula C9H14N2S, MW 182.29 g/mol) for analytical method development and quality control.

Structurally, 1-Methyl-3-(thiophen-3-yl)piperazine (C9H14N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 182.29 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.

As a certified reference material (CRM), 1-Methyl-3-(thiophen-3-yl)piperazine 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.
