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. A variety of complexes are known with bidentate ligands. The tyield is about 85%. Molecular weight calculation: 30.973761 + 18.9984032*5 ›› Percent composition by element. The type of uses and classifications may vary between different submissions to ECHA and for a full understanding it is recommended to consult the source data. If there are no lone pairs then the molecular geometry matches the electronic and is trigonal bipyramid. 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. With primary and secondary amines, the adducts convert readily to dimeric amido-bridged derivatives with the formula [PF4(NR2)]2. Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Chloride gas will be created in 0.54 minutes. 3.2, Table A), Directive 2008/68/EC, last amended by Regulation 2019/1243/EU, 25 July 2019, EU.

ECHA organises consultations to get feedback from all interested parties and to gather the widest possible range of scientific information for the regulatory processes. Such notifications are required for hazardous substances, mixtures, or articles, manufactured or imported at over 1 kg per annum. The CLP Regulation makes sure that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union. Berry pseudorotation influences the 19F NMR spectrum of PF5 since NMR spectroscopy operates on a millisecond timescale. Single-crystal X-ray studies indicate that the PF5 has trigonal bipyramidal geometry. Substances listed in the EINECS, ELINCS, or NLP inventories. REACH registration dossiers have greater data requirements (such as supporting studies) than do notifications under CLP.

ECHA maintains the C&L Inventory, but does not review or verify the accuracy of the information. It is a colourless, water-sensitive and moisture-sensitive solid, although commercial samples can be yellowish and contaminated with hydrogen chloride.. If generated, an InChI string will also be generated and made available for searching. The CLP Regulation uses the UN Global Harmonised System (GHS) and European Union Specific Hazard Statements (EUH). It consists of PF 5 molecules in which each fluorine atom is bonded to the phosphorus atom. Likewise the per substance indication of harmonised C&L, Seveso directive, or notified C&L regulatory context will be made available as soon as possible.
