<p>Applications N-Butyl-N-methylnitrosamine, is an nitroso impurity found in “Sartans” , a class of drugs that block the action of angiotensin.<br> Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package<br></p>

<p>7-[5-(Fluoro-methyl-phosphoryl)oxypentyl]-4-nitro-2,1,3-benzoxadiazole is a reactivator of the central nervous system. It is a noncompetitive antagonist at muscarinic receptors and blocks postsynaptic acetylcholine release from cholinergic neurons. It has been shown to have no effect on blood pressure but does cause an increase in locomotor activity in animals. This drug binds to the hippocampal formation and the ventral hippocampus, which are areas of the brain that are involved in memory and spatial navigation. The distribution of this drug postulated to be due to its ability to penetrate micron sized openings in cell membranes.</p>

<p>N,N'-Di-boc-(L)-cystine-dimethyl ester is a fine chemical that can be used as a versatile building block. It is a complex compound with CAS No. 77826-55-2 and can be used as a reagent or speciality chemical in research. This chemical is also useful for the synthesis of various compounds and has been proven to be an excellent scaffold for chemical reactions.</p>

<p>2-Amino-3-methylpyridine is a colorless crystalline compound. It has the molecular formula of CHN and a molecular weight of 115.2 g/mol. 2-Amino-3-methylpyridine has an asymmetric carbon atom, so it is chiral and can be found in two different forms, enantiomers. The intermolecular hydrogen bond between nitrogen atoms is responsible for the high melting point of -40°C. The coordination geometry of group P2 is pyramidal with the nitrogen atom at the apex and two hydrogen atoms bonded to each other on either side of the nitrogen atom at 120° angles. X ray crystal structures have shown that 2-amino-3-methylpyridine exists as a molecule with an acylation reaction mechanism and intramolecular hydrogen bonding. Methanol solvent was used in this study to dissolve 2 amino 3 methyl pyridine because it does not react with copper chloride</p>

<p>2-Methoxy 17b-estradiol is a synthetic estrogen that binds to DNA and alters the transcriptional process. It has been shown to induce apoptosis by activating the pro-apoptotic protein Bax and inhibiting the anti-apoptotic protein Bcl-2. This drug inhibits the metabolic response of cancer cells to chemotherapy, leading to a decrease in tumor size, and can be used as an implantable device for treating cancer. 2-Methoxy 17b-estradiol also has minimal toxicity in comparison to other estrogens, with no significant cytotoxicity observed in cells of reproductive tissues or endocrine organs, nor any significant toxic effects on liver function tests or serum lipids.</p>

<p>(Fluoro-Methylphosphoryl)Oxycyclohexane is an organophosphorus compound that acts as a nerve agent. It inhibits the enzyme acetylcholinesterase, which is responsible for breaking down acetylcholine, leading to excess cholinergic stimulation. This can cause excessive contraction of muscles or even death. The exposure to (Fluoro-Methylphosphoryl)Oxycyclohexane can be detected by analytical methods such as gas chromatography/mass spectrometry. Oximes are used in the reactivation of acetylcholinesterase and are effective in preventing neuronal death. They bind to the phosphonyl group in (Fluoro-Methylphosphoryl)Oxycyclohexane and prevent it from inhibiting the enzyme acetylcholinesterase.</p>

<p>L-Methionine is a non-essential amino acid that belongs to the group of essential amino acids. It is a major constituent of proteins and is used in the metabolism of lipids, carbohydrates, and nucleic acids. Methionine is also involved in the synthesis of cysteine, which is an important antioxidant. L-Methionine can be found in many foods such as eggs, dairy products, fish, poultry, soybean products, peanuts, beans and seeds. Studies have shown that L-methionine has effects on liver function and may be useful for prevention or treatment of liver disorders such as primary sclerosing cholangitis (PSC). This compound also plays a role in the formation of body tissues and cells. L-Methionine has been shown to increase glutathione levels which are important for detoxification reactions and protection against oxidative stress. It also helps regulate calcium metabolism by reducing calcium absorption from food and increasing excretion via</p>
