C4H13N3 103.17 CAS RN: 111-40-0.—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 × 30-m capillary column coated with G2. The injection port temperature is maintained at 200°; the column temperature is maintained at 100° and programmed to rise 10° per minute to 250° and held there for 5 minutes; and 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 1.4815 and 1.4845 at 20°.
