Chlorali Hydras
C2H3Cl3O2 Mr 165.4
[302-17-0]
DEFINITION
2,2,2-Trichloroethane-1,1-diol.
Content: 98.5 per cent to 101.0 per cent.
CHARACTERS
Appearance: colourless, transparent crystals.
Solubility: very soluble in water, freely soluble in ethanol (96 per cent).
IDENTIFICATION
A. To 10 mL of solution S (see Tests) add 2 mL of dilute sodium hydroxide solution R. The mixture becomes cloudy and, when heated, gives off an odour of chloroform.
B. To 1 mL of solution S add 2 mL of sodium sulfide solution R. A yellow colour develops which quickly becomes reddish-brown. On standing for a short time, a red precipitate may be formed.
TESTS
Solution S. Dissolve 3.0 g in carbon dioxide-free water R and dilute to 30 mL with the same solvent.
Appearance of solution. Solution S is clear (2.2.1) and colourless (2.2.2, Method II).
pH (2.2.3): 3.5 to 5.5 for solution S.
Chloral alcoholate. Warm 1.0 g with 10 mL of dilute sodium hydroxide solution R, filter the supernatant solution and add 0.05 M iodine dropwise until a yellow colour is obtained. Allow to stand for 1 h. No precipitate is formed.
Chlorides (2.4.4): maximum 100 ppm.
Dilute 5 mL of solution S to 15 mL with water R.
Heavy metals (2.4.8): maximum 20 ppm.
10 mL of solution S diluted to 20 mL with water R complies with test A. Prepare the reference solution using lead standard solution (1 ppm Pb) R.
Non-volatile residue: maximum 0.1 per cent.
Evaporate 2.000 g on a water-bath. The residue weighs a maximum of 2 mg.
ASSAY
Dissolve 4.000 g in 10 mL of water R and add 40.0 mL of 1 M sodium hydroxide. Allow to stand for exactly 2 min and titrate with 0.5 M sulfuric acid, using 0.1 mL of phenolphthalein solution R as indicator. Titrate the neutralised solution with 0.1 M silver nitrate, using 0.2 mL of potassium chromate solution R as indicator. Calculate the number of millilitres of 1 M sodium hydroxide used by deducting from the volume of 1 M sodium hydroxide, added at the beginning of the titration, the volume of 0.5 M sulfuric acid used in the 1st titration and two-fifteenths of the volume of 0.1 M silver nitrate used in the 2nd titration. 1 mL of 1 M sodium hydroxide is equivalent to 0.1654 g of C2H3Cl3O2.
STORAGE
In an airtight container.

Chloral Hydrate (CAS: 302-17-0), was first used as a sedative and hypnotic in Germany in the 1870s. Chloral Hydrate is used in the short-term treatment of insomnia (to help you fall asleep and stay asleep for a proper rest) and to relieve anxiety and induce sleep before surgery. It is also used after surgery for pain and to treat alcohol.
Chloral Hydrate is a hypnotic and anticonvulsant. Hypnotic dose can induce sleep within 30 minutes, the hypnotic effect is mild, does not shorten REMS sleep, no obvious aftereffects. The hypnotic mechanism may be similar to that of barbiturates, causing approximate physiological sleep without obvious after-effect. Larger doses have anticonvulsant effects and can be used for convulsions caused by high fever, tetanus and epilepsy in children. Large doses can cause coma and anesthesia. Inhibit the respiratory and vasomotor centers of the medulla oblongata, leading to death.
