Discontinued product2,4,4’-Trichlorobiphenyl
CAS:Controlled Product2,4,4’-Trichlorobiphenyl is a polychlorinated biphenyl congener. It has been shown to have an adverse effect on the central nervous system, causing neurotoxicity. 2,4,4’-Trichlorobiphenyl has been used as a model system for the study of the effects of environmental toxins on mitochondrial membrane potential and lipid peroxidation. 2,4,4’-Trichlorobiphenyl binds to fatty acids in mitochondria and inhibits fatty acid β-oxidation. The inhibition of fatty acid oxidation leads to increased levels of protocatechuic acid in the serum and liver tissue. 2,4,4’-Trichlorobiphenyl has also been found to be toxic to aquatic organisms such as fish and shrimp at low concentrations.

Discontinued product(±)-3-Methyl-2-oxovaleric acid
CAS:(±)-3-Methyl-2-oxovaleric acid is a fatty acid that is found in the mitochondria of liver cells and other tissues. It is an intermediate in the citric acid cycle and can be converted into acetyl-CoA, which is used for energy production. (±)-3-Methyl-2-oxovaleric acid has been shown to cause necrotic cell death when it binds to the mitochondrial membrane potential and causes a loss of ATP production. This results in a lack of energy for the cell, leading to cell death. (±)-3-Methyl-2-oxovaleric acid has also been shown to inhibit protein synthesis by decreasing uptake and increasing creatine kinase activity. This inhibition leads to decreased body formation and tissue culture growth in vitro. In vivo, (±)-3-Methyl-2-oxovaleric acid causes primary sclerosing cholangitis, a disease characterized by inflammation of bile ducts that

CAS:Valeric acid is a fatty acid that is used in the manufacture of polymers. Valeric acid can be synthesized from caproic acid, which is found in palm oil and coconut oil. Valeric acid has been shown to inhibit the activity of nicotinic acetylcholine receptors at low concentrations and to have an inhibitory effect on the ryanodine receptor at high concentrations. Valeric acid also has a matrix effect on analytical methods such as gas-liquid chromatography, which has been modeled using polymer compositions.

Discontinued productL-Aspartic acid alpha-tert-butyl ester
CAS:L-Aspartic acid alpha-tert-butyl ester is a synthetic amino acid that can be used as a substrate for the synthesis of L-cysteine in the presence of selenomethionine. This compound is an auxotroph and cannot be synthesized by the body, so it must be obtained through diet or supplementation. It has been shown to have anti-cancer properties, which may be due to its role in regulating cell proliferation, apoptosis, and angiogenesis. L-Aspartic acid alpha-tert-butyl ester may also inhibit colon cancer cells by preventing them from recycling proteins. This compound was shown to inhibit HCT116 human colon cancer cells in both experimentally and computationally studies. Additionally, this molecule was seen to induce tumor regression in mice with colitis by inhibiting eukaryotic protein synthesis. This inhibition was found to be mediated through a trifluoromethyl group on the molecule's

Discontinued product2-Bromo-3'-hydroxyacetophenone
CAS:2-Bromo-3'-hydroxyacetophenone is a molecule that has been shown to be cytotoxic and effective in inhibiting the growth of cancer cells. 2-Bromo-3'-hydroxyacetophenone inhibits the production of kynurenine, an amino acid that is used in the production of proteins, by competitively binding to the enzyme IDO1. This binding prevents the conversion of tryptophan into kynurenine, leading to cell death. The cytotoxicity of 2-bromo-3'-hydroxyacetophenone was also confirmed by testing its ability to inhibit cellular interaction with human erythrocytes (blood cells) and by measuring its effects on crystallography efficiency.

CAS:(+)-B-Chlorodiisopinocampheylborane is a chiral organoboron reagent that can be used for the enantioselective synthesis of amines. It is prepared from the reaction of chlorodiphenyl borane with (+)-diaminobenzene in hexane. The product can be purified by column chromatography or recrystallization. (+)-B-Chlorodiisopinocampheylborane can also be used in the synthesis of other compounds, such as pyrroles and pantolactones. It is an excellent catalyst for the dehydration of primary amines to give unsymmetrical ketones. This reagent has been shown to be effective in asymmetric hydrogenation reactions, such as the reduction of chiral secondary alcohols, and is also capable of catalyzing aldol reactions.Formula:C20H34BClPurity:Min. 95%Color and Shape:Clear LiquidMolecular weight:320.75 g/molp-Cresol
