(N-Aminohomopiperidine, 1-Aminohomopiperidine), C6H14N2 114.19 CAS RN®: 5906-35-4.-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 0.25-mm x 30-m capillary column coated with G2. The injection port temperature is maintained at 180°; the column temperature is maintained at 80° and programmed to rise 10° per minute to 230° and then maintained at 230° for 5 minutes. The detector temperature is maintained at 300°. The area of the main peak is not less than 95% of the total peak area.
REFRACTIVE INDEX (831): between 1.4840 and 1.4860 at 20°.
