Ethylene glycol CAS#107-21-1阅读更多
Ethylene glycol is the simplest aliphatic dihydric alcohol with chemical properties of alcohols such as being capable of generating ether, ester, or being oxidized into acid or aldehyde as well as being condensed to form ether or being substituted by halogen. Its reaction with acyl chloride or acid anhydride generally forms di-esters. Under heating in the presence of catalyst (manganese dioxide, aluminum oxide, zinc oxide or sulfuric acid), it can be subject to intermolecular or intramolecular dehydration to form the cyclic ethylene acetals, which can react with nitric acid to generate glycol dinitrate (an explosive). Ethylene glycol is the raw material for production of polyester resins, alkyd resins and polyester fiber. It can also be used as the refrigerant agent for automobile and aircraft engines refrigerant. In 1980, the glycol amount used as refrigerant agent is equal to the amount consumption for producing polyester. In addition, it can also be used for synthesizing polymers such as polyester fibers. Ethylene glycol dinitrate, when used in combination with nitroglycerine can reduce the freezing point of explosives. Ethylene glycol can also be used as the raw material of pharmaceuticals and plastics and high-boiling solvents. Industry applied ethylene as a raw material with first converting it to ethylene oxide and then hydrolyzing to produce ethylene glycol.

Usually used in combination with ethylene glycol monostearate (EGMS, ethylene glycol stearate).
Ethylene glycol distearate is synthesized from ethylene glycol and stearate. The response temperature of the standard synthesis procedure is high, generally between (150 ?? 210 ?? C). In order to remove the water produced by the reaction, steps such as nitrogen circulation, minimized pressure or azeotropic dehydration are called for. Due to the high reaction temperature, serious carbonization and also deep color of the item, extra decolorization procedure is required. There are studies using p-toluenesulfonic acid as well as phosphorous acid (molar ratio 1:1) as a composite driver (hereinafter described as composite stimulant) for esterification, as well as the 3 factors of catalyst usage, reaction temperature level, and response time are experimentally researched.

HEPES Buffer CAS #7365-45-9阅读更多
HEPES buffer(4 ?C (2-hydroxyethyl) ?C 1-piperazine ethanesulfonic acid) is a zwitterionic sulfonic acid buffer; One of good??s 20 buffers. Hepes buffer is widely used in cell culture, mainly because it can maintain physiological pH value better than bicarbonate buffer, which is also commonly used in cell culture, although the concentration of carbon dioxide (produced by aerobic respiration) changes. Lepe Zuniga et al. An unwanted photochemical process in which hepes buffer produces hydrogen peroxide when exposed to ambient light is reported, which is not a problem in bicarbonate based cell culture buffer. Therefore, it is strongly recommended to place the solution containing hepes buffer in the dark as far as possible to prevent oxidation.

Huperzine A CAS# 102518-79-6阅读更多
Huperzine A is a natural plant extract. Compared with similar AD treatment drugs approved by the US FDA, Huperzine A has a unique chemical structure and has extremely high selectivity to inhibit acetylcholinesterase in the brain and enhance cholinergic in the brain. function of neurons. In addition, Huperzine A has obvious effects on improving memory and improving cognitive ability.
Huperzine A has a small relative molecular weight, high lipid solubility, and is easy to pass through the blood-brain barrier. After entering the central nervous system, it is mostly distributed in the frontal lobe, temporal lobe, hippocampus and other parts of the brain. Its pharmacological effects have multiple targets. In addition to inhibiting the activity of acetylcholinesterase, it can also antagonize oxidative stress and apoptosis induced by ??-amyloid peptide (A??), hydrogen peroxide and other neurotoxins, by activating the protein kinase C (PKC) signal transduction pathway. Activation of ??-secretase promotes the decomposition of ??-amyloid precursor protein (APP) in a non-amyloidogenic manner to produce sAPP??, reducing A??-mediated toxicity, while sAPP?? can effectively promote cell proliferation, axonal growth, and protect nerves. cell.
