molecular complexity in the synthetic sense. In addition, other factors may be involved in determiningthe difficulty of a problem. For instance, the density of that complexity and the novelty of thecomplicating elements relative to previous synthetic experience or practice are i[r]
need for heating means that there is also an energy cost for producing the feedstockfor polymerization. Once we have a supply of the appropriate monomer (and any otherreagents that may be needed), we will have to pay to transport them to the plant wherethe polymer will be produced. That cost[r]
the nucleus of 109 to produce 110. Since 110 was generated by modifying TGT 109 simply tointroduce a substructural retron, it can be described as a substructure goal (SS-goal) for retrosyntheticanalysis. The connection between 109 and 110 can be sought by either retrosynthetic search orbidire[r]
The formulation development of oral liquid solutions presents many technical problems to theindustrial pharmacist. Special techniques are required to solubilize poorly water- soluble drugs.Solubilization of poorly water-soluble drugs has been a very important issue in screening studies[r]

1.1 What This Chapter Should Teach You To understand that chemical measurements are made for a purpose, usually to answer a nonchemical question. To define measurement and related terms. To understand types of error and how they are estimated. What makes a valid analytical measurement. 1.2 M[r]
patience in further analysis are essential. After a synthetic plan is selected the chemist must choose thechemical reagents and reactions for the individual steps and then execute, analyze and optimize theappropriate experiments. Another aspect of molecular complexity becomes apparent[r]
Most analytical experiments produce measurement data which require to be presented, analysed, and interpreted in respect of the chemical phenomena being studied. For such data and related analysis to have validity, methods which can produce the interpretational information sought need[r]
Bioassay guided fractionation led to the isolation of a new triterpene glycoside, holothurinogenin B (1) along with three known compounds, holothurin B (2), holothurin A (3), and holothurin A2 (4), from the methanol extract of the Vietnamese sea cucumber Holothuria scabra. Their structures were dedu[r]
