Chemical Structure

3-Methoxyphenylacetylene 3-Ethynylanisole 1-Ethynyl-3-methoxybenzene 768-70-7 CAS 768-70-7 chemical structure

Description

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.

3-Methoxyphenylacetylene 3-Ethynylanisole 1-Ethynyl-3-methoxybenzene 768-70-7 (CAS 768-70-7) is a high-purity analytical reference standard with the molecular formula C9H14O and a molecular weight of 138.21 g/mol.

Based on its molecular formula C9H14O, 3-Methoxyphenylacetylene 3-Ethynylanisole 1-Ethynyl-3-methoxybenzene 768-70-7 contains a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 138.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
