The Sodium salicylate, with the CAS registry number 54-21-7, is a kind of white powder. This is easily soluble in water(1：0.8，25℃) and glycerol while insoluble in ether, chloroform and  benzene. Being stable chemically while incompatible with mineral acids and metallic salts, this chemical is light-sensitive.

The physical properties of Sodium salicylate are as follows: (1)ACD/LogP: 2.06; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -0.93; (4)ACD/LogD (pH 7.4): -1.09; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 1; (8)ACD/KOC (pH 7.4): 1; (9)#H bond acceptors: 3; (10)#H bond donors: 2; (11)#Freely Rotating Bonds: 2; (12)Polar Surface Area: 46.53; (13)Flash Point: 144.5 °C; (14)Enthalpy of Vaporization: 61.16 kJ/mol; (15)Boiling Point: 336.3 °C at 760 mmHg; (16)Vapour Pressure: 4.45E-05 mmHg at 25°C; (17)Exact Mass: 160.013639; (18)MonoIsotopic Mass: 160.013639; (19)Topological Polar Surface Area: 60.4; (20)Heavy Atom Count: 11; (21)Complexity: 138.

The production method of Sodium salicylate: Add salicylic acid and sodium bicarbonate into the distilled water with the temperature of 60℃, and then add EDTA and sodium hydrosulfite with defined amount; Next heat it to 85℃ and react for about half an hour; Lastly filter the qualified reaction liquid into the fluidized bed and then dry to 85℃ to get this product.

As to its usage, it is widely applied in many ways. It could be used in organic synthetic materials, antiseptic, the reagent testing the gastric acid in the free agents; It could also be used as the drug with the function of being antifebrile and anti-rheumatic. In addition, it is also a potential replacement for aspirin for people sensitive to it.

When you are dealing with Sodium salicylate , you should be much more cautious. For one thing, it is irritant to eyes, respiratory system and skin, which may also cause inflammation to the skin or other mucous membranes. For another thing, it is harmful which may cause damage to health and it may have risk of serious damage to eyes. Therefore, you should wear suitable protective clothing. If in case of contact with eyes, rinse immediately with plenty of water and seek medical advice.

In addition, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: C1=CC=C(C(=C1)C(=O)[O-])O.[Na+]
(2)InChI: InChI=1S/C7H6O3.Na/c8-6-4-2-1-3-5(6)7(9)10;/h1-4,8H,(H,9,10);/q;+1/p-1
(3)InChIKey: ABBQHOQBGMUPJH-UHFFFAOYSA-M
