Sodium salicylate is a sodium salt of salicylic acid. It can be prepared from sodium phenolate and carbon dioxide under higher temperature and pressure. Historically, it has been synthesized from methyl salicylate (found in wintergreen plants or the bark of sweet birch tree) by reacting it with an excess of sodium hydroxide and heating it under reflux.

Sodium salicylate is of the salicylate family and this compound is known to trigger Reye's Syndrome in children and adults, usually following a viral infection such as influenza or chicken pox. Products containing such salicylates should not be given to children under the age of 19.

Sodium salicylate, HOC6H4COONa, is a shiny, white powder with sweetish taste and mild aromatic aroma that is soluble in water,glycerol, and alcohol.Used in medicine and as a preservative.

In manufacture of aspirin, methyl salicylate, and other salicylates. Coupling agent for azo dyes. Has been used as food preservative.

It is used in medicine as an analgesic and antipyretic. Sodium salicylate also acts as non - steroidal anti - inflammatory drug (NSAID), and induces apoptosis in cancer cells and also necrosis. It is also a potential replacement for aspirin for people sensitive to it. It may also be used as a phosphor for the detection of vacuum ultra violet radiation and electrons.

keratolytic

A salt or ester of salicylic acid.

Sodium salicylate may be prepared by the reaction, in aqueoussolution, by adding equal molar ratio of salicylic acidand sodium bicarbonate; evaporating to dryness yields thewhite salt. In solution, particularly in the presence of sodiumbicarbonate, the salt will darken on standing. This is the saltof choice for salicylate medication and usually is administeredwith sodium bicarbonate to lessen gastric distress, or itis administered in enteric coated tablets. However, the useof sodium bicarbonate is ill advised, because it decreases theplasma levels of salicylate and increases the excretion offree salicylate in the urine.
Sodium salicylate, even though not as potent as aspirinfor pain relief, also has less GI irritation and is useful for patientswho are hypersensitive to aspirin.

Cell permeable: yes

30 g of sodium hydroxide is dissolved in 300 ml of water, to which 100 g of salicycilic acid is then added with agitation. The agitation is continued for a while to dissolve the salicylic acid completely and then the solution is evaporated to dryness to obtain 110 g of sodium salicylate.
