CAS 119-36-8 Methyl Salicylate oil

Methyl salicylate oil is an organic compound formed by the combination of the hydroxyl group of methanol and the carboxyl group of salicylic acid, also known as wintergreen oil (refined from holly tree). It is a slightly yellowish liquid with a peculiar smell of herbs, sweet and spicy, with a physical property of melting at -8.6 ° C and a boiling point of 218-224 ° C (partial decomposition during boiling). Medicinal mainly as topical redness agent, commonly used in swelling, pain, but later because of the iron-ion activity in the blood and other related side effects, it is rarely used for oral medication, mainly aspirin Replaced. It has a local stimulus, can promote local blood circulation, topical or local rub can produce skin vasodilation, redness and other irritation, and the reflex of the corresponding parts of the skin, muscles, nerves and joints, which play to eliminate Swollen, anti-inflammatory and analgesic effects, but also itching effect. Can be used for sprains, contusions, back pain, muscle pain, neuralgia, itching.

Hydrogen ions on the carboxyl group of salicylic acid are attracted and transferred by the OH group of methanol and protonated thereby to form an excellent leaving group on the hydroxyl group of methanol. However, the carboxyl group of salicylic acid The hydroxyl substitution reaction SN2, because methanol is a host of quality, very unfavorable SN1 substitution reaction, the formation of methyl salicylate, which is considered as an esterification reaction.

Usage:

Salicylate ointment is a kind of common dermatology medicine, has analgesic, antiphlogistic, bactericidal action, because can produce local stimulation, very few internal clothing. Applied to the skin is easy to absorb, its liniment, ointment can be used in acute rheumatoid arthritis, low back pain and muscle pain, can also be used to stop itching. It can also be used as a correction agent, aromatic agent and preservative.
