[(E)-[(Thiophen-3-yl)methylidene]amino]thiourea CAS 1161720-10-0

Description

Compared with other compounds in its class, the molecular weight of 185.27 g/mol gives [(E)-[(Thiophen-3-yl)methylidene]amino]thiourea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

[(E)-[(Thiophen-3-yl)methylidene]amino]thiourea (CAS 1161720-10-0) is a high-purity analytical reference standard with the molecular formula C6H7N3S2 and a molecular weight of 185.27 g/mol.

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, [(E)-[(Thiophen-3-yl)methylidene]amino]thiourea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.27 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
