Orthogonally positioned diamino pyrrole- and imidazole-containing polyamides: synthesis of 1-(3-substituted-propyl)-4-nitropyrrole-2-carboxylic acid and 1-(3-chloropropyl)-4-nitroimidazole-2-carboxylic acid was written by Satam, Vijay;Patil, Pravin;Babu, Balaji;Rice, Toni;Porte, Alexander;Alger, Shannon;Zeller, Matthias;Lee, Moses. And the article was included in Synthetic Communications in 2014.HPLC of Formula: 5930-92-7 This article mentions the following:
Pyrrole- and imidazole-containing oligoamides can be tailored to recognize the DNA 6-8 base pair sequence. Adding a second amino group via the N(1)-position of pyrrole or imidazole in oligoamides could enhance their DNA-binding affinity and water-solubility while retaining sequence specificity. Synthesis of the key 1-substituted 4-nitropyrrole (and imidazole)-2-carboxylic acid building blocks are described. In the experiment, the researchers used many compounds, for example, Ethyl 4-nitro-1H-pyrrole-2-carboxylate (cas: 5930-92-7HPLC of Formula: 5930-92-7).
Ethyl 4-nitro-1H-pyrrole-2-carboxylate (cas: 5930-92-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.HPLC of Formula: 5930-92-7
