C11H14O 162.23 CAS RN®: 1009-14-9. - Colorless liquid.
Assay: Inject an appropriate specimen into a suitable gas chromatograph (see Chromatography 〈621〉) equipped with a flame-ionization detector, helium being used as the carrier gas. The following conditions have been found suitable: a capillary column coated with a 1-μm layer of phase G2; the injection port temperature is maintained at 250°; the detector temperature is maintained at 300°; and the column temperature is maintained at 150° and programmed to rise 10° per minute to 300°. The area of the C11H14O peak is not less than 98% of the total peak area.
Refractive Index 〈831〉: 1.5149 at 20°.
Boiling Range: between 105° and 107°, at a pressure of 5 mm of mercury.
