1. p-Methoxybenzoic acid
English name:Anisic aci
dCAS number:100-09-4
Methoxybenzoic acid, also known as p-anisic acid, 4-anisic acid, and anisic acid, is a colorless needle-shaped crystal at room temperature, soluble in ethanol, ether, and chloroform, slightly soluble in hot water, and insoluble in water. In cold water. The intermediate p-methoxybenzoyl chloride of amiodarone is prepared by chlorination with thionyl chloride. It is used as a pharmaceutical intermediate of Solaracetam, and can also be used as a spice and preservative.
2. p-Nitrobenzyl bromide
English name: Stannic chloride pentahydrate
CAS number:10026-06-9
Crystalline tin chloride, also called crystalline tin tetrachloride, tin chloride, tin tetrachloride, chemical formula SnCl4, formula weight 260.53. Colorless fuming liquid, acidic. It dissolves in water and releases a lot of heat. Its dilute aqueous solution will produce stannic acid precipitation due to hydrolysis. It is freely miscible with alcohol, carbon disulfide and turpentine. The absorption of chlorine gas is very large.

8.Sodium monofluorophosphate
English name: Disodium monofluorophosphate
CAS number:10163-15-2
Sodium monofluorophosphate ("MFP" for short) is a white powdery solid with a melting point of about 626°C. It is easily soluble in water and has strong hygroscopicity. Its solubility in water at 25°C is 42%. There is no rusting effect. The pH value of 2% aqueous solution is 6.5 to 8.0. The aqueous solution undergoes slow hydrolysis when boiling, which can lead to a decrease in bound fluorine and an increase in free fluorine, so the purity is reduced.
Application: Sodium monofluorophosphate is widely used and is mainly used in toothpaste additives, concrete corrosion inhibitors, food, medical treatment, etc.
