Miscellaneous Aldehydes

Salicylaldehyde is a skin irritant 500 mg/day caused moderate irritation to rabbit skin. It can have injurious effects on fertility. Studies on rats indicate that subcutaneous administration of salicylaldehyde in a high dose of 400 mg/kg can produce developmental abnormalities, fetal death, and postimplantation mortality. 

The toxicity of this compound, however, is low. No toxic symptoms were noted. 

LD50 valne, oral (rats) 520 mg/kg LD50 value, skin (rats) 600 mg/kg 

Combustible liquid flash point 78°C (172°F) fire-extinguishing agent alcohol foam. The range for its explosive limits in air is not reported. 

Salicylaldehyde is burned in a chemical incinerator equipped with an afterburner and scrnbber.
