The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. Substances may have impurities and additives that lead to different classifications. If at least one company has indicated that the substance classification is affected by impurities or additives, this will be indicated by an informative sentence. You’ve supercharged your research process with ACS and Mendeley! Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed.

When information is available in all sources, the first two are displayed as a priority. ACS members enjoy benefits including 50 free articles a year and reduced priced individual subscription.

This substance has been found in the following regulatory activities (directly, or inheriting the regulatory context of a parent substance): Willkommen auf der Website der ECHA! ECHA maintains the C&L Inventory, but does not review or verify the accuracy of the information. It does not represent a new labelling, classification or hazard statement, neither reflect other factors that affect the susceptibility of the effects described, such as duration of exposure or substance concentration (e.g. The molecular structure is based on structures generated from information available in ECHA’s databases. the Altmetric Attention Score and how the score is calculated.

Students then test their hypothesis by performing the reaction with different catalyst quantities and at different temperatures. Dies ist eine einzigartige Informationsquelle zu Chemikalien, die in Europa hergestellt oder dorthin eingeführt werden. The EC Number is the numerical identifier for substances in the EC Inventory.
