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.

Velvet Bean

Product name:Velvet Bean
Description:Velvet Bean is a natural source of the amino acid, l-dopa.

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.

Appearance: Blue-black crystals
Product description: Anthracycline-based anticancer drug, anticancer activity and adriamycin similar or slightly higher, significantly higher than that of cyclophosphamide, cytarabine, methotrexate, fluorine urea pyrimidine, vincristine and other commonly used anticancer drugs.Clinically used breast cancer has prominent curative effect.

Vemurafenib

Product name:Vemurafenib
CAS: 918504-65-1
Molecular Formula: C23H18ClF2N3O3S
Molecular weight:489.9221264
Appearance:white powder
Stability:Stable
Shelf life:2 years
Product description :Vemurafenib is a type of cancer treatment called a cancer growth blocker. Vemurafenib is given for melanomas that have a change (mutation) in a gene called BRAF. The change in this gene leads to the production of a changed (mutated) BRAF protein. This protein helps melanoma tumours grow.Vemurafenib blocks (inhibits) the changed BRAF protein, which can stop the melanoma cells from growing and dividing.

Venus Flytrap extract

Product name:Venus Flytrap extract
Description:The Venus flytrap is a perennial plant that traps and eats insects. It is native to the low-lying wetlands of the southeastern United States. After being harvested, the whole fresh plant is pressed to remove the liquid extract, which is used as an herbal remedy. It is also used in mixtures like Carnivora, a patented formula that includes many ingredients in addition to Venus flytrap extract. Venus flytrap extract is sold in capsule and liquid form to be taken by mouth and as an injectable liquid.
