1,3-Thiazole-4,5-dicarbaldehyde 2465AE 39669-78-8 C5H3NO2S (CAS 39669-78-8), molecular formula C5H3NO2S and molecular weight 141.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,3-Thiazole-4,5-dicarbaldehyde 2465AE 39669-78-8 C5H3NO2S (C5H3NO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
