Description of key information
Additional information
In aquatic systems, heptanoyl chloride (CAS 2528 -61 -2) hydrolyses quickly and forms HCl (CAS 7647-01-0) and heptanoic acid (CAS 111 -14 -8) (for details see section 5.1.2).
Short-term toxicity to fish
Parent compound heptanoyl chloride: With high probability acutely not harmful to fish after pH-adjustment (96 -h LC50 > 100 mg/L).
Short-term toxicity to aquatic invertebrates
Parent compound: no data available
RA to CAS 3282 -30 -2: With high probability acutely not harmful to aquatic invertebrates (48-h EC50 = 203 mg/L, pivalic acid).
Toxicity to aquatic algae and cyanobacteria
Parent compound heptanoyl chloride: No data available.
RA to CAS 3282 -30 -2: With high probability acutely not harmful to aquatic algae (72 -h ErC50 = 979 mg/L, NOEC = 246 mg/L, pivalic acid).
Toxicity to microorganisms
Parent compound heptanoyl chloride: No reliable data.
Hydrolysis product heptanoic acid: The inhibition of the degradation activity of activated sludge is not anticipated
when introduced in appropriate low concentrations (40 -h EC50 = 169 mg/L).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
