Chemical Structure
Description
The occurrence of 2-Thiophenecarboxaldehyde, 5-ethenyl- is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Thiophenecarboxaldehyde, 5-ethenyl- (CAS 90110-08-0), molecular formula C7H6OS and molecular weight 138.19 g/mol, is a CATO reference standard with documented purity and traceability.
2-Thiophenecarboxaldehyde, 5-ethenyl- (C7H6OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
