| Description | P-Anisidine, also known as 4-methoxyaniline or p-aminoanisole, belongs to the class of organic compounds known as aminophenyl ethers. These are aromatic compounds that contain a phenol ether, which carries an amine group on the benzene ring. P-Anisidine is a very strong basic compound (based on its pKa). If heated strongly, it may release very toxic fumes of nitrogen oxides. P-Anisidine is a polyphenol compound found in foods of plant origin (A15261). P-Anisidine is a potentially toxic compound. P-Anisidine is the most toxic of the three isomers of anisidine and causes blood damage upon oral ingestion, inhalation or skin contact. P-Anisidine reacts with secondary oxidation products such as aldehydes and ketones in fats and oils. p-Anisidine was first documented in 1995 (PMID: 18966208). These are organic compounds contaiing a methoxybenzene or a derivative thereof (PMID: 12643317) (PMID: 12929121). |
