Sigma-Aldrich
Sigma-Aldrich (formally MilliporeSigma) is an American chemical, life science, and biotechnology company that is owned by the German chemical conglomerate Merck Group. Sigma-Aldrich was created in 1975 by the merger of Sigma Chemical Company and Aldrich Chemical Company. It grew through various acquisitions until it had over 9,600 employees and was listed on the Fortune 1000. The company is headquartered in St. Louis and has operations in approximately 40 countries. In 2015, the German chemical conglomerate Merck Group acquired Sigma-Aldrich for $17 billion. The company is currently a part of Merck's life science business and in combination with Merck's earlier acquired Millipore Corporation, Millipore, operates as MilliporeSigma. History Sigma Chemical Company of St. Louis and Aldrich Chemical Company of Milwaukee were both American specialty chemical companies when they merged in August 1975. The company grew throughout the 1980s and 1990s, with significant expansion in fac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amine
In chemistry, amines (, ) are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines). Important amines include amino acids, biogenic amines, trimethylamine, and aniline; Inorganic derivatives of ammonia are also called amines, such as monochloramine (). The substituent is called an amino group. Compounds with a nitrogen atom attached to a carbonyl group, thus having the structure , are called amides and have different chemical properties from amines. Classification of amines Amines can be classified according to the nature and number of substituents on nitrogen. Aliphatic amines contain only H and alkyl substituents. A ...

Herbicides
Herbicides (, ), also commonly known as weedkillers, are substances used to control undesired plants, also known as weeds.EPA. February 201Pesticides Industry. Sales and Usage 2006 and 2007: Market Estimates. Summary in press releasMain page for EPA reports on pesticide use ihere Selective herbicides control specific weed species, while leaving the desired crop relatively unharmed, while non-selective herbicides (sometimes called total weedkillers in commercial products) can be used to clear waste ground, industrial and construction sites, railways and railway embankments as they kill all plant material with which they come into contact. Apart from selective/non-selective, other important distinctions include ''persistence'' (also known as ''residual action'': how long the product stays in place and remains active), ''means of uptake'' (whether it is absorbed by above-ground foliage only, through the roots, or by other means), and ''mechanism of action'' (how it works).

1-Amino-2-propanol
1-Aminopropan-2-ol is the organic compound with the formula CH3CH(OH)CH2NH2. It is an amino alcohol. The term ''isopropanolamine'' may also refer more generally to the additional homologs diisopropanolamine (DIPA) and triisopropanolamine (TIPA). 1-Aminopropan-2-ol is chiral. It can be prepared by the addition of aqueous ammonia to propylene oxide. Biosynthesis (''R'')-1-Aminopropan-2-ol is one of the components incorporated in the biosynthesis of cobalamin. The ''O''-phosphate ester is produced from threonine by the enzyme Threonine-phosphate decarboxylase. Applications The isopropanolamines are used as buffers. They are good solubilizers of oil and fat, so they are used to neutralize fatty acids and sulfonic acid-based surfactants. Racemic 1-aminopropan-2-ol is typically used in metalworking fluid, waterborne coatings, personal care products, and in the production of titanium dioxide and polyurethanes. It is an intermediate in the synthesis of a variety of pharmaceutical dru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diisopropanolamine
Diisopropanolamine is a chemical compound with the molecular formula used as an emulsifier, stabilizer, and chemical intermediate. Diisopropanolamine can be prepared by the reaction of isopropanolamine or ammonia with propylene oxide Propylene oxide is an acutely toxic and carcinogenic organic compound with the molecular formula CH3CHCH2O.
