BOD5*100/COD provides substance information on the substance’s BOD5*100/COD values displayed in O2 (milli)gram per gram test material. The data presented in these sections has been cleaned to remove names of one character or less, or names which consist solely of punctuation or numerical characters. There is broad agreement in that a majority of data submitters agree this substance is Skin sensitising (100% of REACH registrations). The regulation aims to protect human health and the environment by banning or severely restricting the production and use of persistent organic pollutants in the European Union. H dimensionless volumetric basis provides substance information on the substance’s Henry’s Law Constant in dimensionless volumetric basis at a temperature measured in °C and a pressure measured in Pascal. Data is generally displayed in milligram per litre air. Values are presented in (nano/ micro/milli)gram per litre and/or (nano/ micro/milli)molar per litre. Displayed are the RANGES of min – max of the PRIORITISED value(s) within the five highest priority groupings of provided data. See ‘Summary effect on fertility oral route’, except: This section displays the values related to neurotoxicity from all registered dossiers for the substance. EC50/LC50 for microorganisms provides substance information on the substance’s effect concentration or lethal concentration for 50% of the microorganisms in the test, generally displayed in milligram per litre. Solubility in organic solvents / fat solubility. Tetrahydrophthalic anhydride, the cis isomer, is prepared by the Diels-Alder reaction of butadiene and maleic anhydride. Solubility in organic solvents at 20°C provides substance information on the substance solubility in organic solvents in gram per litre at a temperature of 20°C. If so, the data provided is not processed for the Brief Profile. If such information is available in ECHA’s database and is it not claimed confidential, the molecular formula and molecular structure will be displayed here. Registrants can choose from the following picklist endpoint conclusions/effect levels: Respiratory irritation provides substance information on the substance’s irritation effect on the respiratory system. Autoflammability / Self-ignition provides substance information on the substance’s self-ignition temperature in °C  at a pressure measured in Pascal. Note: If a temperature value is not provided by the registrant, the information on half-life in water will not be processed for the Brief Profiles. This substance is used in the following activities or processes at workplace: closed processes with no likelihood of exposure, closed, continuous processes with occasional controlled exposure, closed batch processing in synthesis or formulation, batch processing in synthesis or formulation with opportunity for exposure, transfer of chemicals at dedicated facilities, transfer of substance into small containers, laboratory work and manual maintenance (cleaning and repair) of machinery. This section summarises physical and chemical property values from all registered dossiers in ECHA’s databases for the substance. The regulation aims improve the protection of human health and the environment from the risks that can be posed by chemicals, while enhancing the competitiveness of the EU chemical industry. 1.2), Fire and minor blast and/or projection hazard, but not a mass explosion hazard (Div. Data from all dossiers registered and the Classifications and Labelling Inventory (C&L) for the same substance are used to generate the Brief Profile. For more information on total tonnage band calculation please consult the Data submission manual. Processable data for study results is prioritised by test species (see list below) and subsequently further prioritised by the dose descriptor. Processable data is prioritised by the toxicity descriptor type (see list below) and subsequently further prioritised by duration (in hours, longer prioritised over shorter). Values are generally displayed in milligrams per kilogram (dry weight). Phototransformation in soil provides substance information on the substance’s phototransformation in soil in seconds/minutes/hours/days/weeks/months/years. If more than one IUPAC name is available from REACH registered dossiers, all IUPAC names are displayed in ‘Other names’ section of the Brief Profile. Processable data is prioritised by the toxicity descriptor type (see list below) and subsequently further prioritised by duration (longer prioritised over shorter). The Hazard classification and labelling section uses the signal word, pictogram(s) and hazard statements of the substance under the harmonised classification and labelling (CLH) as its primary source of information. Insoluble in water and denser than water. Hence sinks in waters. listed below. Furthermore, updates in the source data may not always result in an update of the Brief Profile. Release to the environment of this substance can occur from industrial use: manufacturing of the substance. Within each of these categories, data is prioritised further by duration (in hours), with longer prioritised over shorter. 1), Substances or mixtures which in contact with water release flammable gases which may ignite spontaneously (Cat.1), Self-heating substances and mixtures (Cat.2), Substances or mixtures which in contact with water release flammable gases which may ignite spontaneously (Cat.2), Substances or mixtures which in contact with water releases flammable gases (Cat.3), Substances and mixtures which in contact with water emit flammable gases, Contact with water liberates highly flammable gases, Spontaneously flammable in air (pyrophoric), Projection hazard but not a mass explosion hazard (Div. If so, the data provided is not processed for the Brief Profile.Prioritization by test species: Processable data for the summary is prioritised by test species (see list below) and subsequently further prioritised by the dose descriptor.
