List by Name

The most complete listing of chemicals in commerce is Chem Sources published annually by the Directories Publishing Company, Flemington, New Jersey. This volume lists by name all commercially available chemicals with addresses of suppliers. 

Federal and State laws define waste as hazardous if it is ignitable, corrosive, reactive, or toxic. Other wastes are listed by name. These may differ from lists of hazardous materials, which are regulated by OSHA and Right-to-Know. The Standard Industrial Classifications (SICs) of a physician s medical office and a dentist s office are 8011 and 8021, respectively. 

Elements Listed by Name, Symbol, and Atomic Number... 

A cylinder containing CH4, CiHe, and N2 has to be prepared containing a mole ratio of CH4 to CjHfi of 1.5 to 1. Available are (1) a cylinder of a N2-CH4 mixture (80% N2, 20% CH4), (2) a cylinder of 90% N2 and 10% CiHe, and (3) a cylinder of pure N2. List the total number and names (or symbols) of the unknown quantities and concentrations, and list by name the balances that you would use to solve this problem (do not make the balances). What is the residual number of degrees of freedom that have to be specified to make the problem completely determined (i.e., have a unique solution) ... 

Methods for loop prediction are listed. When publicly available programs can be identified, they have been listed by name. Some methods have been implemented in publicly available programs, but no specific software or scripts are available. 

For example, an alcohol not listed by name in the Hazardous Materials Table, which meets the definition of a Flammable liquid can be assigned the proper shipping names Alcohol, n.o.s., or Flammable liquid, n.o.s. The identification numbers and specific packing requirements for these entries are different. The regulation requires the selection of Alcohol, n.o.s, as the proper shipping name, since this name best describes the material to be shipped. 

Substances are listed by name, either an lUPAC systematic name or, in the case of drugs and other complex compounds, a common synonym. Inorganic compounds, including metal salts of organic acids, are listed first, followed by organic compounds. The molecular formula in the HUl convention is included. 

This table gives selected properties of some important amino acids and closely related compounds. The first part of the table lists the 20 standard amino acids that are the basic constituents of proteins. The second part includes other amino acids and related compounds of biochemical importance. Within each part of the table the compounds are listed by name in alphabetical order. Structures are given in the following table. 

For biotechnology, the most important provision of TSCA is the section 5(a) requirement that companies notify EPA at least 90 days before beginning to manufacture or import a "new chemical substance" for commercial purposes. This reporting requirement is known as premanufacture notification or PHN. Any substance that is not listed by name on EPA s Chemical Substances Inventory or that is not "naturally occurring" is defined as "new" and therefore subject to PMN requirements. 

Many fluorocarbon compounds are listed by name in the regulations of DOT and TC, and those not listed can be shipped under refrigerant and dispersant gas, n.o.s. entries [9, 10]. At one time, the prefix mono was used in DOT listings to show the presence of one atom of the indicated element, but it is omitted in modem terminology. The prefix mono is not acceptable on documents in Canada.
