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. For example, monoprotic acids (a compound that is capable of donating one proton per molecule) are compounds that are capable of donating a single proton per molecule. Sulfated and tungstated stannias were prepared from commercial Sn-gels of meta-stannic acids; the former showed catalytic activities higher than those of the materials obtained from conventional gels and of sulfated zirconias.The latter led to the synthesis of a ceramics acid, calcined at >1000 °C, whose catalytic activity and acidity were intermediate between mordenite and silica–alumina. Substances listed in the EINECS, ELINCS, or NLP inventories. Metastannic Acid on heating gives. The latter led to the synthesis of a ceramics acid, calcined at >1000 °C, whose catalytic activity and acidity were intermediate between mordenite and silica–alumina. Acids differ in the number of protons they can donate. The source of the information is mentioned in the introductory sentence of the hazard statements.

More information about CAS and the CAS registry can be found here. 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. Sulfated stannia (SO4/SnO2) obtained by drying meta-stannic acids (supplied by Koujundo Kagaku and Yamanaka) at 200 °C, followed by exposing to 3 M H2SO4 and calcining at 300 °C showed catalytic activities higher than those of the materials obtained from conventional gels (preparation of stannia gels from SnCl4 and calcination at 500 °C) for the dehydration of methanol and the isomerization of butane. in case of consumer and professional uses). We apologise for the inconvenience in the meantime. Carbon dioxide, salt, and water are produced when ethanoic acid reacts with carbonates and hydrogen carbonates. Substances for which classification and labelling data have been notified to ECHA by manufacturers or importers. According to the reading, metastannic tin can be precipitated with the addition of sulfuric acid.

This information is only displayed if the substance is well-defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure. Harmonised classification and labelling is a legally binding classification and labelling for a substance, agreed at European Community level. The EC or list number is the primary substance identifier used by ECHA. Registration, Evaluation, Authorisation and Restriction of Chemicals, Chemical Agents Directive and Carcinogens or Mutagens Directive, EC Inventory, Pre-Registration process, Other, Substances of very high concern identification, Recommendation for the Authorisation List, Getting started with EU chemicals legislation, Classification of substances and mixtures, Harmonised classification and labelling (CLH). The Support section provides tools and practical guidance to companies which have responsibilities under the EU chemicals legislation. The CLP Regulation ensures that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union through classification and labelling of chemicals. ECHA organises consultations to get feedback from all interested parties and to gather the widest possible range of scientific information for the regulatory processes.
