	Chemical Nomenclature
		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.
		When naming binary covalent compounds formed between two nonmetals, another system of nomenclature is preferred in which the numbers of each atom in a molecule are specified by a Greek prefix.

	Chemical Names for Compounds
		One is the reason for having a systematic method for naming chemical compounds.
		Chemical names like sodium chloride, magnesium oxide, mercuric sulfide, nitrous oxide and cupric sulfate do a better job of conveying information about what elements are contained in a compound.
		These are Stock names and the Roman numeral tells us about the condition (charge or oxidation state) of the element it follows.

	Chemical substance - Wikipedia, the free encyclopedia
		The concept of a chemical substance became firmly established in the late eighteenth century after work by the chemist Joseph Proust on the composition of some pure chemical compounds such as basic copper carbonate.
		No chemical process occurs, and the material can be identified as a mixture by the fact that the sulfur and the iron can be separated by a mechanical process, such as using a magnet to attract the iron away from the sulfur.
		Finally, chemical analysis may be used to identify the chemical composition and to assay the purity.

	C471 Lecture: Chemical Name and Formula Searching
		Chemical Abstracts Service's Registry File is the single largest collection of data that can be used to identify a chemical substance.
		It may be a new method of preparation, a new source for the substance, a new reaction, a new kinetic or mechanistic study, new chemical or physical properties, a new method of analysis, a new use or application, or a new biological effect.
		Chemical reactants and the resulting products are routinely indexed, but reagents are not indexed unless there is a new prepartion of the reagent itself or a novel use of a standard reagent.

	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.
		It is also preferable that the name convey some information about the structure or chemistry of a compound.
		An international conference was convened in Geneva in 1892 by the national chemical societies, from which the first widely accepted proposals for standardization arose.

	ACD/Labs Solutions: Chemical Patenting and Nomenclature Conversion
		Among the most critical factors in patenting chemical compounds are the quality and the comprehensive coverage of the patent.
		Since structures are often named ambiguously in patent literature, having both name-to-structure and structure-to-name conversions, and an ability to choose the appropriate nomenclature standard, is critical for comprehensive prior art reviews.
		To find out how naming software is used by patent attorneys and agents to help conduct comprehensive prior art searches and accurately name novel chemical compounds for patents, read more about the application of ACD/Name for patenting.

	TSCA CHEMICAL SUBSTANCES INVENTORY [52]
		TSCA Chemical Substances Inventory (derived from the Initial Inventory of the Toxic Substances Control Act Chemical Substance Inventory) is a non-bibliographic dictionary listing chemical substances manufactured, imported, or in commercial use in the U.S. The Inventory was developed in response to Section 8(d) of the Toxic Substances Control Act (TSCA), public law 94-469.
		Substance entries in TSCA Chemical Substances Inventory were derived from the May 1985 version of the Inventory and previous versions compiled by the U.S. Environmental Protection Agency, and the supplements of 1988, 1990, 1991 and 1993.
		Because a common name may be used to identify more than one substance, verify the presence of the substance in the Inventory using the CAS Registry Number.
