Organic acid presence of other substituents that affect the polarity of the compound. Simple organic acids like formic or acetic acids are used for oil and gas well stimulation treatments. These organic acids are much less reactive with metals than are strong mineral acids like hydrochloric acid (HCl) or mixtures of HCl and hydrofluoric acid (HF). For this reason, organic acids are used at high temperatures or when long contact times between acid and pipe are needed. The conjugate bases of organic acids such as citrate and lactate are often used in biologically-compatible buffer solutions. Citric and oxalic acids are used as
3-Nitrobenzoic acid 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 1.5% respectively. Since carboxylic acid functional
