N-Octyl-2-pyrrolidone

N-Octyl-2-pyrrolidone is a safe and efficient organic solvents. It can be applied into pesticides, cotton fallen leaves, concentrated cleaning agents, chemical reaction solvents, drug synthesis media, the coating agent in the electronics industry. N-Octyl-pyrrolidone is colorless clear liquid, boiling point 307 Degree C, boiling point 170-172 °C15 mm Hg(lit.)

Paradichlorobenzene PDCB

Paradichlorobenzene PDCB (also called 1,4-Dichlorobenzene and p-dichlorobenene) is an important moth repellent chemicals. It exists in white laminated shape or granulated crystals, insoluble in water,soluble in ethanol,ethyl ether,benzene and other organic solvents. PDCB can be used as pesticide,detergent and produce mothballs.

Sodium methoxide 30% solution & powder 99%

Sodium methoxide exists in two types: 99% pure powder & 30% solution. Sodium methoxide white powder is 4.2 class dangerous chemicals as it is easy to react with oxygen and it will divide into methanol and sodium hydroxide when meet moisture or air. It is soluble in methanol and ethanol. Sodium methoxide 30% solution is colourless to slightly yellowish, viscous liquid.

Chlorhexidine digluconate 20% solution

Chlorhexidine digluconate is well known for its funtion of disinfection and sterilization. The common existance at market is 20% solution which appears almost transparent colorless or pale yellow slightly sticky liquid, miscible with water, soluble in acetone and in alcohol.

Sodium borohydride powder/granule

As a strong reducing agent, Sodium borohydride exists in 98% solid & 12% solution in appearance. For solid form, it is soluble in water and alcohol (ethanol & methanol). But we have to know one thing: Sodium borohydride is dangerous chemicals. It reacts readily with water and eaction may be violent. It is incompatible with water, oxidizing agents, carbon dioxide, hydrogen halides, acids, palladium, ruthenium and other metal salts, glass etc.

Piperazine Anhydrous

Piperazine Anhydrous is an important intermediate for medicine, dyes and pesticide. We have two kinds of piperazines: pharmaceutical grade & indutrial grade. Both types are white crystal flakes in appearance, freely soluble in water, ethylene glycol and glycerine, insoluble in diethyl ether. But pharma grade is higher purity and lower impurities (water & other contents) than industrial grade.

Phenacetin powder

Phenacetin is glossy flaky crystalline powder, without odor, slightly bitter taste. Melting point 137-134. Stable in air, soluble in water, slightly soluble in ether, soluble in ethanol, chloroform. It is made by reduction of p-chloronitrobenzene via process of etherification, and acetylation reaction. Phenacetin is antipyretic and analgesic agent, suitable for fever, headache, neuralgia etc.

Menadione powder

Menadione (Vitamin K3) has a diuretic, enhance liver detoxification function, involved in membrane structure, lower blood pressure function. It is also indispensable to bone hormone synthesis process. It exists in white crystalline powder.
