Amount of substance in use in chemical engineering in the United States is the pound-mole, having the symbol lb-mol. One pound-mole is . When quoting an amount of substance, it is necessary to specify the entity involved, unless there is no risk of ambiguity. One mole of chlorine could refer either to chlorine atoms, as in 58.44 g of sodium chloride, or to chlorine molecules, as in 22.711 liters of chlorine gas at STP. The simplest way to avoid ambiguity is to replace the term "substance" by the name of the entity or to quote the empirical formula. For example: Amount of substance
Compound management journal articles devoted entirely or in part to compound management. It has become a critical technological component for high-throughput screening and chemical genomics. There are great challenges to be faced in the necessity of compound management, which are being surmounted by concerted efforts in the public and private domain. In 2008, authors at the National Institutes of Health's Chemical Genomics Center have released a paper showing the necessity of a highly automated, reliable and parallel compound management platform, in order to serve over 200,000 different compounds. In short, Compound Management requires inventory control of small molecules and biologics needed for
