Description and Uses

Crystalline leaflets or a white, crystalline powder having a bitter taste. It is soluble in 25 parts of water, slightly soluble in hot alcohol, and soluble in diluted mineral acids and in alkaline solutions. It sublimes at between 168°C and 170°C, and melts with decomposition at about 284°C. The pH of a 1 in 100 solution is between 5.5 and 7.0.
Absolute: The absolute is prepared by alcoholic extraction of the concrete in approximately 55 to 60% yields. The absolute consists of a semisolid, olive-green mass with a characteristic ambergris odor.
Resinoid and Resin Absolute: The resinoid consists of the hydro carbon extract of the crude resin. The resin absolute consists of the alcoholic extract of the crude labdanum resin. Since this prod uct is a semisolid, nonpourable mass, a high-boiling, odorless solvent may be added prior to evaporation of the alcohol to prepare a pourable liquid.

L-Isoleucine may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using high-performance liquid chromatography technique.
