CH3COOCH=CH2 86.09 CAS RN®: 108-05-4. - Liquid.
Assay: Inject an appropriate volume into a 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 0.25-mm × 30-m capillary column coated with a 1-μm layer of G2; the injection port temperature is maintained at 100°; the detector temperature is maintained at 300°; and the column temperature is maintained at 100° and programmed to rise 10° per minute to 150°. The area of the CH3COOCH=CH2 peak is not less than 99% of the total peak area.
