Solubility test— One mL is miscible with 1 mL of chloroform without turbidity. Add 20 mL of 90 percent alcohol to this mixture: the resulting liquid is neutral or acid to moistened litmus paper and, upon standing at 20, deposits crystals within 5 minutes.

Specific gravity 841: between 0.848 and 0.863 at 30 compared with water at 15.

Angular rotation 781A: between 1 and 4.

Refractive index 831: between 1.457 and 1.463 at 30.

Residual solvents 467: meets the requirements.
