Nucleic acid thermodynamics of base incompatibility by quantifying the temperature at which two strands anneal can provide information as to the similarity in base sequence between the two strands being annealed. The complexes may be dissociated by thermal denaturation, also referred to as melting. In the absence of external negative factors, the processes of hybridization and melting may be repeated in succession indefinitely, which lays the ground for polymerase chain reaction. Most commonly, the pairs of nucleic bases A=T and G≡C are formed, of which the latter is more stable. DNA denaturation, also called DNA melting, is the process by which double-stranded deoxyribonucleic
2-Iodobenzoic acid 2-Iodobenzoic acid 2-Iodobenzoic acid, or "o"-iodobenzoic acid, is an organic compound with the formula ICHCOOH. The synthesis of 2-iodobenzoic acid "via" the diazotization of anthranilic acid is commonly performed in university organic chemistry labs. One of its most common uses is as a precursor for the preparation of IBX and Dess–Martin periodinane, both used as mild oxidants. 2-Iodobenzoic acid can be synthesized "via" a Sandmeyer reaction consisting of the diazotization of anthranilic acid followed by a diazo replacement. First anthranilic acid is treated with nitrous acid in order to convert the amino group into the diazo group. The diazo group
