C23H46O2 354.61 CAS RN®: 929-77-1.-White powder.
Assay: Inject an appropriate specimen into a gas chromatograph (see Chromatography (621)) equipped with a thermal conductivity detector, helium being used as the carrier gas. The following conditions have been found suitable: a 2.0-mm x 1.8-m glass column packed with 5% G3 phase on support S1A; the injection port temperature is maintained at 300°; the detector temperature is maintained at 300°; the initial temperature of the oven is 220°, which is held for 2 minutes, and then programmed to rise 3º per minute to attain a final temperature of 270°, which is held for 10 minutes. The area of the C23H46O2 peak is not less than 98% of the total peak area.
MELTING RANGE (741): between 54° and 56°.
