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. NMR Data for Alcohols : NMR Index : Alcohol IR PDB: ethanol: 1-propanol: 2-propanol: 1-butanol: 2-butanol: 2-methyl-1- propanol: 1-pentanol: 2-pentanol: 3-pentanol: 3-methyl-1- butanol
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. Contact Us The molecular structure is based on structures generated from information available in ECHA’s databases.
The EC Inventory is a combination of three independent European lists of substances from the previous EU chemicals regulatory frameworks (EINECS, ELINCS and the NLP-list).
REACH registration dossiers have greater data requirements (such as supporting studies) than do notifications under CLP. ORL-RAT LD50 1870 mg kg-1, SKN-RBT LD50 2520 mg kg-1, DANGER: FLAMMABLE, causes narcosis, irritation.
