Reagent inventories

Inosine 5 -Monophosphate Dehydrogenase. A series of 21 known inosine 5 -monophosphate dehydrogenase (IMPDH) inhibitors was used to validate a virtual screening protocol. By application of a molecular weight filter (80 < MW < 400), 3425 compounds were extracted from an in-house reagent inventory system. Docking of these compounds into a substrate-IMPDH complex 3D structure was performed with the program FlexX three... 

A chemical and reagent inventory module that manages the purchase and use of laboratory supplies, keeps track of lot number purchases, shelf lives, and costs. 

Manages reaction schemes and batches. Tracks reactants, products, conditions and reaction progress. Searches reactants and products structures or properties. Provides links to lab notebooks, compound databases, and reagent inventory. 

Manages reagent inventory. Tracks amounts and withdrawal history. Links to vender databases. Supports multi-level locations and stock room functionalities. Tracks safety information and provide reports for meeting regulations. 

As mentioned earlier, although SX is a mature and well-developed art, the process possesses several drawbacks whilst the process is efficient and relatively cheap, it is of considerable environmental and public health concern because of the use of large amounts of diluents which are o ften volatile, flammable and toxic. Additionally, the substantial reagent inventory required by solvent extraction processes has driven study into more efficient extractive separation technologies. In particular, a great deal of research into new forms of membrane systems has been undertaken. 

To apply Equation, we need complete inventories of the bonds present in all the reagents that participate in the reaction. We build such inventories from sfructural formulas, from which we count the number of bonds of each type. The procedures for generating sfructural formulas are not introduced until Chapter 9, so we provide the correct structures for examples in this chapter. 

Safety. As well as the reduced inventory of chemicals and solvents, highly exothermic reactions can be safely handled because of the excellent heat flow properties of a flow reactor and the fact that smaller quantities of reactants are present at any time. Similarly, toxic reagents are present in smaller quantities and require minimum handling. 

Reagents and standards—inventory all reagents, standards, and supplies to determine acceptability with method requirements and specifications. 

The second class of TAM RE AC s inventory includes the reactions between the coordinated ligands and external organic reagents. We divide these reactions into nucleophilic and electrophilic attacks and consider them as acid-base interactions. Table III presents their general description. The nucleophilic attacks are either addition reactions to unsaturated coordinated ligands (Reactions 44-46) or abstraction reactions (usually a proton abstraction, Reactions 47-50). The electrophilic attacks are similarly addition reactions (Reactions 51 and 52) and abstraction reactions (usually a hydride abstraction, Reactions 53-59). Reactions 60 to 63 represent some other intermolecular reactions. 

Produced HBr is scrubbed by the use of 10 N sodium hydroxide solution to form sodium bromide. For all the runs, the initial inventory is 1.25 L of sodium hydroxide solution. The NaOH solution was sampled at regular intervals and sent to Argonne s Analytical Chemistry Laboratory for analysis. Volume aliquots of solution samples were diluted with reagent water and analysed by ion chromatography to determine bromide. Separate aliquots were diluted with acid addition and analysed by inductively coupled plasma-atomic emission spectrometry (ICP-AES) to determine calcium. During the data analysis, adjustments are made for the addition of condensed unreacted steam to the neutralisation solution. 

Analysis of the time spent planning, rehearsing and making libraries can identify scope to improve productivity and also what information may be of most value to other scientists. Ordering and managing the inventory of reagents can be time-consuming and often requires additional functionality (discussed later) not found in older inventory databases.
