Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 99.15 g/mol gives Thiophen-2(3H)-imine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Thiophen-2(3H)-imine (CAS 82357-68-4), a certified reference material (molecular formula C4H5NS, MW 99.15 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, Thiophen-2(3H)-imine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 99.15 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), Thiophen-2(3H)-imine 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.
