EC number: 218-212-9
CAS number: 2082-59-9
The test item does not contain any functional groups which can be
protonated or deprotonated significantly in aqueous solution.
With the computer program ACD/pKa DB ( Advanced Chemistry Development
Inc., Toronto, Canada) a pKa value could not be calculated.
Therefore, the substance is to be considered a neutral molecule in the
pH range 2 ¿ 10, which is of relevance for aqueous biological systems.
Pentanoic anhydride does not contain any functional groups which can be protonated or deprotonated significantly in aqueous solution. Therefore, the substance is to be considered a neutral molecule in the pH range 2-10, which is of relevance for aqueous biological systems.
