Chemical Structure

3-Ethyl-1-phenylhept-1-yn-3-ol CAS 19781-33-0 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

3-Ethyl-1-phenylhept-1-yn-3-ol (CAS 19781-33-0) is a high-purity analytical reference standard with the molecular formula C15H20O and a molecular weight of 216.32 g/mol.

3-Ethyl-1-phenylhept-1-yn-3-ol (C15H20O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
