The physical state and form of a substance can play a significant impact when the hazards of a substance are assessed. By summarising the endpoint study data, ECHA aims to make this information accessible in a user-friendly way in line with the Agency’s goals and standards. Registrants can choose from the following picklist endpoint conclusions/effect levels: This section displays the values related to sensitisation from all registered dossiers for the substance. If so, the data provided is not processed for the Brief Profile. Does anybody know the pKb of sodium hydride, or the pKa of its conjugate acid? More detailed information is available in the dossiers. This section summarises the pH values from all registered dossiers for the substance. Sodium hydride (60% dispersion in mineral oil) (NaH) can be used for a variety of applications such as: • preparation of a plasticizer for the formation of a solid polymer electrolyte (SPE) for optoelectronic application • synthesis of heteroaryl thioethers, the common constituents in therapeutic compounds Values are generally displayed in milligram per litre. Dossier evaluation – indicated if at least one registered dossier for the substance has been evaluated under REACH for compliance check or testing proposal evaluation and associated decision(s) published on the ECHA website.
