		Chemical Waste Satellite Accumulation Areas are designated with a CWSAA poster (available online or by contacting EHS) in conjunction with the use of a secondary containment.
		Abbreviations, chemical nomenclature, and molecular formulas are not acceptable means for identifying the constituents of the waste container.
		Containers from household products are not made to the same chemical resistance standards as those used for chemicals, and may not maintain their integrity when used to contain laboratory reagent chemicals or chemical waste.

	Nomenclature and Registry Systems for Biopharmaceuticals and Biogenerics
		Similarly, there are no nomenclature or registry systems capable of appropriately handling biotechnology or biopharmaceutical products, which as entities exhibit much more complexity than chemical substances and drugs, with this further complicated by their complex and often-changing regulatory and commercial aspects (that combine to define them as products).
		Systematic chemical nomenclature (names) is similarly a method for linear notation or representation of chemical structures (with trivial/common or derivative names adopted where this fails).
		By their very nature, nomenclature systems tend to collect names varying greatly in their specificity and accuracy, often including names that are simply wrong, but have been used in the literature or other source(s) the registry system is intended to serve.

	Chemical Nomenclature
		Before a systematic method of naming different chemical substances was established, various compounds were named after people, places, or things.
		Chemical nomenclature is the systematic naming of chemical compounds.
		So far we have seen that in the name of a chemical compound, the first element usually is positive, and is the first part of the name.

	Chemical Nomenclature (Site not responding. Last check: 2007-10-20)
		Chemical Nomenclature is the science of determining names and formulas of chemical substances.
		The identity of each atom (that is, which chemical element it belongs to) is determined by the number of protons in the atom's nucleus.
		Since the chemical symbol of mercury (Hg) is taken from the Latin name hydragyrum, you might expect its two ions to be named hydragyrous ion and hydragyric ion.

	Chemical Nomenclature Translation
		Systematic nomenclature is one of the oldest forms of line notation.
		Any software that can convert systematic nomenclature, such as IUPAC names, into a computer-based representational system, such as a connection table, has the potential to unlock vast amounts of legacy chemical information by making it structure-searchable.
		Nomenclature translation has been more widely investigated than the related problem of 2-D raster image interpretation, although the driving forces in both cases are the same.

		Chemical nomenclature simply means the naming of chemical compounds.
		Chemical elements, which are the simplest forms into which materials can be resolved by chemical means, react with each other to yield chemical compounds containing various proportions of two or more elements.
		Because organic chemistry is the study of carbon-hydrogen compounds, organic compounds are named by giving the chain or other structure of the carbon-hydrogen atoms and substituting into that structure the names of any other elements or groups of elements and the particular places at which they are present.

	International Union of Pure and Applied Chemistry nomenclature - Wikipedia, the free encyclopedia
		IUPAC nomenclature is a system of naming chemical compounds and of describing the science of chemistry in general.
		The primary function of chemical nomenclature is to ensure that the person who hears or reads a chemical name is under no ambiguity as to which chemical compound it refers: each name should refer to a single substance.
		While both explanations are probably valid to some extent, it is remarkable that the first "modern" system of chemical nomenclature appeared at the same time as the distinction (by Lavoisier) between elements and compounds, in the late eighteenth century.

	The First Chemical Revolution
		The first chemical revolution was spurred by the work of Lavoisier and Berzelius, who transformed the archaic language of chemists into a system understandable by people with little formal education.
		The first chemical revolution took place when the ancient and obscure art of chemistry was revealed to the masses by the efforts of Lavoisier and Berzelius.
		This system of nomenclature and the formulae describing its use were first introduced in Annals of Philosophy in 1814, and were adopted in textbooks beginning in 1832.
