Chemical Structure
Description
CATO supplies 3-(Prop-2-yn-1-yloxy)benzofuran-2-carboxylic acid (CAS 1774901-65-3), a certified reference material (molecular formula C12H8O4, MW 216.19 g/mol) for analytical method development and quality control.
Structurally, 3-(Prop-2-yn-1-yloxy)benzofuran-2-carboxylic acid (C12H8O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 216.19 g/mol, it falls into the medium-molecular-weight range. 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.
