(2-Propenoic Acid; Vinylformic Acid), C3H4O2 72.06 CAS RN®: 79-10-7.—Colorless liquid. Miscible with water, with alcohol, and with ether.
Assay: Inject an appropriate specimen into a gas chromatograph (see Chromatography〈621〉), equipped with aflame-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 phase G2; the injection port temperature is maintained at 150°; the detector temperature is maintained at 300°; and the column temperature is maintained at 50° and programmed to rise 10° per minute to 200°. The area of the C3H4O2 peak is not less than 99% of the total peak area.
Refractive Index〈831〉: between 1.419° and 1.423° at 20°.
