Zinc bromide is sometimes used for the selective removal of Boc protecting groups from secondary amines. It is possible that a harmonisation is introduced through an amendment to the CLP Regulation. in case of consumer and professional uses). endstream endobj 32 0 obj<. machine wash liquids/detergents, automotive care products, paints and coating or adhesives, fragrances and air fresheners), outdoor use, indoor use in close systems with minimal release (e.g. It is the electrolyte in the zinc bromide battery. Occupational exposure limit (OEL) values are derived within two legal frameworks that form an integral part of the EU’s mechanism for protecting the health of workers. It covers their hazardous properties, classification and labelling, and information on how to use them safely. The Prior Informed Consent Regulation administers the import and export of certain hazardous chemicals and places obligations on companies who wish to export these chemicals to non-EU countries. 0000009920 00000 n Other release to the environment of this substance is likely to occur from: indoor use (e.g. 0000006096 00000 n the products in which the substance may be used) may refer to uses as intermediate and under controlled conditions, for which there is no consumer exposure. The reaction mixture was stirred at RT for 3 days, after which time it was . More information about Classification and Labelling is available in the Regulations section of ECHA website. Substances which have been registered and can be placed on the EEA market by those companies with a valid registration. Category. Precautionary statements - describe recommended measures to minimise or prevent adverse effects resulting from exposure to a hazardous product or improper storage or handling of a hazardous product. 1. n. [Drilling Fluids] A acidic salt, ZnBr 2, which is used to prepare dense, clear (solids-free) brine for well completion and workover operations. The use information is displayed per substance life cycle stage (consumer use, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites or in manufacturing). Note that for readability purposes, only the pictograms, signal words and hazard statements referred in more than 5% of the notifications under CLP are displayed. It is blended with calcium chloride/calcium bromide brines to formulate and control the density of various fluid blends. Its HSE problems must be weighed carefully against its advantages. The REACH registered substance data and the C&L Inventory portal will be upgraded from the 9th November. 0000055458 00000 n If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9. ECHA organises consultations to get feedback from all interested parties and to gather the widest possible range of scientific information for the regulatory processes. The ‘Hazard classification and labelling’ section shows the hazards of a substance based on the standardised system of statements and pictograms established under the CLP (Classification Labelling and Packaging) Regulation. inside a watch) or with very low concentrations considered not to pose risks to human health or the environment. Additionally, if available, information on the use of the substance and how consumers and workers are likely to be exposed to it can also be displayed here. 2.5kg 2.5kg (1) Filter. This is unique source of information on the chemicals manufactured and imported in Europe. Zinc Bromide/Calcium Bromide brine is used as a clear-fluid brine during workover and completion operations which require densities to 19.2 lb/gal (2,301 kg/m3). 0 0000003248 00000 n Danger! This substance is used in the following areas: mining and municipal supply (e.g. If available, additional information on classification and labelling (C&L) is derived from REACH registration dossiers submitted by industry. * Skin rash can occur with repeated exposure. Refine Selection By. Substances indicated, in 2009, as being intended to be registered by at least one company in the EEA. A substance identified primarily by an EC or list number may be linked with more than one CAS number, or with CAS numbers that have been deleted. Such notifications are required for hazardous substances, mixtures, or articles, manufactured or imported at over 1 kg per annum. 0000004127 00000 n BPR regulation aims to improve the functioning of the biocidal products market in the EU, while ensuring a high level of protection for humans and the environment. It is 75% clear brine and has the chemical formula ZnBr2. The molecular structure is based on structures generated from information available in ECHA’s databases. The moderate yield that resulted from the Grignard reagents could be improved using more nucleophilic lithium reagents (65%). It is the responsibility of the substance manufacturers and importers to consult official publications, e.g. In oil and natural gas wells, solutions containing zinc bromide are used to displace drilling mud when transitioning from the drilling phase to the completion phase or in well workover operations. cooling liquids in refrigerators, oil-based electric heaters) and outdoor use in close systems with minimal release (e.g. The source of the information is mentioned in the introductory sentence of the hazard statements. <<2646060013328f46b9b6dda348e2aa0d>]>> More information about CAS and the CAS registry can be found here.
