Peracetic acid Peracetic acid Peracetic acid (also known as peroxyacetic acid, or PAA), is an organic compound with the formula CHCOH. This organic peroxide is a colorless liquid with a characteristic acrid odor reminiscent of acetic acid. It can be highly corrosive. Peracetic acid is a weaker acid than the parent acetic acid, with a p"K" of 8.2. Peracetic acid is produced industrially by the autoxidation of acetaldehyde: It forms upon treatment of acetic acid with hydrogen peroxide with a strong acid catalyst: As an alternative, acetyl chloride and acetic anhydride can be used to generate a solution of the acid with
Chemical compound microarray Chemical compound microarray A chemical compound microarray is a collection of organic chemical compounds spotted on a solid surface, such as glass and plastic. This microarray format is very similar to DNA microarray, protein microarray and antibody microarray. In chemical genetics research, they are routinely used for searching proteins that bind with specific chemical compounds, and in general drug discovery research, they provide a multiplex way to search potential drugs for therapeutic targets. There are three different forms of chemical compound microarrays based on the fabrication method. The first form is to covalently immobilize the organic compounds on the solid
