C10H12O2 164.20 CAS RN: 1676-63-7.—White to tan crystals.
Assay: Dissolve about 50 mg in 1 mL of ether. Inject about 1 μL of this solution into a suitable gas chromatograph (see Chromatography 〈621〉) equipped with a flame-ionization detector and a 0.25-mm × 30-m capillary column containing stationary phase G1. The carrier gas is helium. The chromatograph is programmed as follows. Initially, the column temperature is equilibrated at 180°, then the temperature is increased at a rate of 10° per minute to 280°, and maintained at 280° for 10 minutes. The injection port temperature is maintained at 280°, and the detector is maintained at 300°. The area of the 4′-ethoxyacetophenone peak is not less than 97.5% of the total peak area.
Melting Range 〈741〉: between 34° and 39°.
