Organic acid anhydride case, the name of the acyl group is enclosed in parentheses to avoid ambiguity in the name, e.g., (thioacetic) anhydride (CHC(S)OC(S)CH). When two acyl groups are attached to the same sulfur atom, the resulting compound is called a thioanhydride, e.g., acetic thioanhydride ((CHC(O))S). Organic acid anhydride An organic acid anhydride is an acid anhydride that is an organic compound. An acid anhydride is a compound that has two acyl groups bonded to the same oxygen atom. A common type of organic acid anhydride is a carboxylic anhydride, where the parent acid is a carboxylic acid, the formula of the anhydride
3-Nitrobenzoic acid methemoglobin, sensitisation, irritation, and corneal damage. 3-Nitrobenzoic acid 3-Nitrobenzoic acid is an organic compound with the formula CH(NO)COH. It is an aromatic compound and under standard conditions, it is an off-white solid. The two substituents are in a meta position with respect to each other, giving the alternative name of m-Nitrobenzoic acid. This compound can be useful as it is a precursor to 3-aminobenzoic acid, which is used to prepare some dyes. It is prepared by nitration of benzoic acid at low temperatures. Both 2-Nitrobenzoic acid and 4-Nitrobenzoic acid are produced as side products, with yields of approximately 20% and
