Urea
Product name:Urea
CAS: 57-13-6
Molecular Formula: H2NCONH2
Molecular Weight: 60.06
Product description:A composed of carbon, nitrogen, oxygen and hydrogen organic compounds, molecular formula for H2NCONH2. Also known as urea, carbon amide, carbamide urea, white odourless solid, melting point 133-135 ℃, relative density 1.323 (20/4 ℃), soluble in water and ethanol, strong thermal decomposition into ammonia and carbon dioxide. In 1773 by the Lyle ROM el (Hilaire Rouelle) found. Creatures with carbon dioxide, water, aspartic acid and ammonia and other chemical synthesis of urea.A fine chemical fertilizer, after applied into the soil under the effect of urease, slow hydrolysis release ammonia and carbon dioxide, absorbed by plants. (soy contains a large amount of urease, is the first time obtains the crystal type of enzyme, is very important in the development of biochemistry) it is also an important chemical raw material manufacturing drugs and plastic.

Venlafaxine
Product name:Venlafaxine
CAS: 93413-69-5
Molecular Formula: C17H27NO2
Molecular Weight: 277.4
Product description:Mainly through the drug at the same time blocking NE reuptake and 5 - HT, higher concentration of NE and 5 - HT and give play to the role of double antidepressant, heavy intake of dopamine (DA), only a slight inhibition. For M choline receptor, adrenaline alpha 1, alpha, beta 2 receptor, histamine H1 receptor almost no affinity. 0 - to its active metabolites methyl enlafaxine may also inhibit 5 - HT and NE heavy intake, activity is lower than prototype drug. Research has shown that this product in small doses is mainly inhibiting the reuptake of 5 - HT, large doses of 5 - HT and NE reuptake inhibition. The drug for 5 - HT reuptake inhibition weaker than selective 5 - HT heavy uptake inhibitor (SSRI); On NE reuptake inhibition is also weak in some tricyclic antidepressants (TCA) or selective NE reuptake inhibitor.
