Danger

H314: Causes severe skin burns and eye damage [Danger Skin corrosion/irritation]

Chemical: Propanoic acid, 3-chloro-

REACH registered substance: 3-chloropropionic acid (EC: 203-534-4)

3-Chloropropionic acid: Does not have an individual approval but may be used under an appropriate group standard

3-CHLOROPROPIONIC ACID reacts exothermically with bases. Reacts with aqueous solutions containing a base and dissolves if neutralization generates a soluble salt. May react with active metals to form gaseous hydrogen and a metal salt. May corrode or dissolve iron, steel, and aluminum parts and containers. Reacts with cyanide salts to generate gaseous hydrogen cyanide. Reacts with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides to generate flammable and/or toxic gases and heat. Reacts with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Reacts with carbonates and bicarbonates to generate a harmless gas (carbon dioxide) but some heat. Can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. A wide variety of products is possible. May initiate polymerization reactions or catalyze other chemical reactions. Fires produces highly toxic chloride fumes (USCG, 1999).
