Chemical Structure
Description
The occurrence of (2E)-3-[5-(methylsulfanyl)thiophen-2-yl]prop-2-enoic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2E)-3-[5-(methylsulfanyl)thiophen-2-yl]prop-2-enoic acid (CAS 773129-18-3) is a high-purity analytical reference standard with the molecular formula C8H8O2S2 and a molecular weight of 200.28 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (2E)-3-[5-(methylsulfanyl)thiophen-2-yl]prop-2-enoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.28 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), (2E)-3-[5-(methylsulfanyl)thiophen-2-yl]prop-2-enoic acid 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.
