Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(But-3-yn-1-yl)-5-methylfuran.
2-(But-3-yn-1-yl)-5-methylfuran (CAS 7051-41-4), molecular formula C9H10O and molecular weight 134.18 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 2-(But-3-yn-1-yl)-5-methylfuran is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 134.18 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.
