Chemical inventories, commercial

Since PTT is a new commercial product, the Shell Chemical Company, as the company which first introduced it to the market, took the responsibility of product stewardship [112], and registered the polymer on the chemical inventory lists in several countries. As a high-molecular-weight polymer, PTT is biologically inactive and requires safe handling like many other commercial polymers. 

CAS Registry Numbers are also widely used as standard identifiers for chemical substances in many of the commercial chemical inventories of governmental regulatory agencies, such as the Toxic Substances Control Act (TSCA) Inventory in the United States, the European Inventory of Existing Commercial Chemical Substances (EINECS), and the Canadian Domestic and Non-Domestic Substance Lists (DSL/NDSL). 

To request a search of the confidential Inventory, the requestor must demonstrate that it has a bona fide intent to manufacture or import the chemical for commercial purposes. Because this information is only available to potential manufacturers and importers, downstream processors and users cannot request a search, and must rely on suppliers for compliance information. 

If you store chemicals in your laboratory, you need to have a chemical inventory that specifies the chemical name, molecular formula, CAS number, source, container size, date received, and location. Individual labs may also track other information about chemicals. Automated chemical inventory systems may require more information. There are commercial inventory systems available and it is likely that you will not have any choice in this selection." ... 

AH of the amyl alcohols are TSCA and EINECS (European Inventory of Existing Commercial Chemical Substances) registered. 

The LD q for sodium bromide taken orally by rats is 3.5 g/kg body weight, and the TD q orally in rats is 720 mg/kg (8). RTECS Hsts data on reproductive effects in male and female rats. Sodium bromide is Hsted in the TSCA Inventory, the Canadian Domestic Substances Hst (DSL), the European Inventory of Existing Commercial Chemical Substances (EINECS), the Japanese Existing and New Chemical Substances (ENCS), and the Korean Existing Chemicals Hst (ECL). It is not regulated by the U.S. Department of Transportation. 

In the European Union, coal-derived complex chemical substances, ie, those contained in the European Inventory of Existing Commercial Chemical Substances, have been classified for carcinogenicity in the twenty-first adaptation to technical progress of the European Commission (EC) Dangerous Substances Directive 1994 67/548/EEC (57). The EC Regulation 793/93 requires data sets to be submitted by producers or importers to the... 

Poly(vinyl chloride) is Hsted on the TSCA inventory and the Canadian Domestic Substances List (DSL) as ethene, chloro-, homopolymer [9002-86-2]. Because polymers do not appear on the European Community Commercial Chemical Substances listing or EINECS, poly(vinyl chloride) is listed through its monomer, vinyl chloride [75-01-4]. In the United States, poly(vinyl chloride) is an EPA hazardous air pollutant under the Clean Air Act Section 112 (40 CER 61) and is covered under the New Jersey Community Right-to-Know Survey N.J. Environmental Hazardous Substances (EHS) List as "chloroethylene, polymer" with a reporting threshold of 225 kg (500 lb). 

All four butanols are registered ia the United States on the Environmental Protection Agency Toxic Substances Control Act (TSCA) Inventory, a prerequisite for the manufacture or importation for commercial sale of any chemical substance or mixture ia quantities greater than a 1000 pounds (454 kg). Additionally, the manufacture and distribution of the butanols ia the United States are regulated under the Superfund Amendments and Reauthorization Act (SARA), Section 313, which requires that anyone handling at least 10,000 pounds (4545 kg) a year of a chemical substance report to both the EPA and the state any release of that substance to the environment. 

One early step in the workflow of the medicinal chemist is to computationally search for similar compounds to known actives that are either available in internal inventory or commercially available somewhere in the world, that is, to perform similarity and substructure searches on the worldwide databases of available compounds. It is in the interest of all drug discovery programs to develop a formal process to search for such compounds and place them into the bioassays for both lead generation and analog-based lead optimization. To this end, various similarity search algorithms (both 2D and 3D) should be implemented and delivered directly to the medicinal chemist. These algorithms often prove complementary to each other in terms of the chemical diversity of the resulted compounds [8].

The Toxic Substances Control Act (TSCA) refers to "new chemicals" as those not on the TSCA Inventory of Chemical Substances which lists about 55,000 existing commercial chemicals. All new chemicals must enter EPA s premanufacture notification program (PMN) for review before manufacture. This program is the most complete record of development of new chemicals by U.S. industry over the past 2 1/2 years. To date over 1,000 notices have been submitted, many including confidential business information (CBI). Despite the CBI, it is possible to summarize EPA s experience with new chemical substances and to evaluate the PMN program and its impact on product innovation. That is essentially the aim of this paper. 

First, of all, I would like to clarify the term "new chemicals." I am referring to the TSCA definition as those chemicals not listed on the TSCA Chemical Substance Inventory and maintained on a daily basis by the Office of Toxic Substances within EPA. This is a list of all commercial chemicals - some 55,000 in all - produced in or imported into the United States during the period of 1975 through 1979. My talk this afternoon will not cover the thousands of formula changes in mixtures of chemicals which occur almost daily as industry tries to meet changing market demands.
