Chemicals

 Chemicals are chemical substances produced or used industrially or in a laboratory. These can be pure substances or mixtures of substances. However, whether a substance is called a chemical depends heavily on the context.

Sources of information on chemicals are listed here as commercial goods - possibly supplemented by legal and official requirements.

For the properties and data of individual chemicals and classes of substances, see under chemical substances.

Commercially Available Chemicals

Pure chemicals and mixtures of substances are used in many areas. The list below can help you to find sources and manufacturers, even for special and hard-to-find products

Chemicals Data Base

A searchable online database of properties, safety data, commercial sources and other essential information for more than 1,000,000 commercially available chemicals. The search is based on any criteria such as substance name, formula, structural formula, various identifiers, CAS, etc.

Traders and distributors for Chemicals

Trading companies that operate in the field of chemical procurement - mostly worldwide and regardless of type and quantity - are listed under Chemicals Trading.

The manufacturers and suppliers listed in the Laboratory Chemicals directory are more specialized in the purest fine chemicals and reagents for research, laboratories, chemical analysis and many other applications.

The manufacture of certain chemicals that are not commercially available or do not meet desired criteria may be commissioned from companies listed under Custom Synthesis.

Regulatory and Security

Handling chemicals is often associated with hazards.

To protect people, animals and the environment, legal regulations apply in most countries and national communities regarding the handling and labeling of hazardous substances.

You can find out about the regulations that apply in a country from the relevant authorities and the legal texts. Some countries also offer extensive information portals on handling chemical substances - both in general and on individual chemicals. Here are a few examples with a wide range of information:

The so-called EU Chemicals Regulation, also known as the REACh Regulation, provides the legal basis for handling chemicals in the countries of the European Community (EU). REACh stands for Registration, Evaluation, Authorization and Restriction of Chemicals.

The REACh system is based on the principle of industry ownership. According to the principle of no data, no market, only chemical substances that have been previously registered may be placed on the market within the scope. Every manufacturer or importer who wants to place his substances that fall within the scope of REACh on the market must have his own registration number for these substances (Further information on the EU chemicals regulation: see under REACh chemicals).

This system results in data and regulations for individual chemicals, mixtures and substance groups, which can be accessed online via a freely accessible database maintained by the European Chemicals Agency (ECHA): Information on Chemicals (ECHA Infocard).

When evaluating chemicals in the United States, the principle of non-hazardous chemical substances applies. In contrast to the EU, substances are not classified into specific categories in the USA. There, the substance only has to be notified to the Environmental Protection Agency (EPA) by means of a Pre-Manufacture Notice (PMN) 30 days before manufacture or import.
