Chemical Structure
Description
(E)-3-(Thiazol-4-yl)acrylaldehyde (CAS 185947-65-3), molecular formula C6H5NOS and molecular weight 139.17 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, (E)-3-(Thiazol-4-yl)acrylaldehyde is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.17 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.
