Description and references

Prepn of analogous compd, p-chlorobenzyl p-nitrobenzyl sulfide, from p-chlorophenylthiol and p-nitrobenzyl chloride: Stevenson et al., GB 738170 (1955 to Boots Pure Drug). Chemical and biological properties: Cranham et al., Chem. Ind. (London) 1953, 1206.

Chemical structure

Properties

Crystals, mp 75-76°. Technical grades may have almond-like odor. d425 1.4210. Vapor tension at 30°: 1.21 × 105 mm. uv max (95% ethanol): 262 nm: Watson, Chem. Ind. (London) 1956, 349. Soly in water <1:5000, in ethanol about 2.9%, in kerosene 5-7.5%. Sol in acetone, benzene, toluene, xylene, petr ether. Resistant to acid and alkaline hydrolysis. Strong oxidizing agents convert it to the corresponding sulfoxide and sulfone.

Caution
