1,3-Dicyclohexylurea (cas: 2387-23-7) belongs to amides. Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.HPLC of Formula: 2387-23-7

Mass spectrometry-based metabolomics approach to reveal differential compounds in pufferfish soups: Flavor, nutrition, and safety was written by Bi, Hongyan;Cai, Dandan;Zhang, Rutan;Zhu, Yiwen;Zhang, Danni;Qiao, Liang;Liu, Yuan. And the article was included in Food Chemistry in 2019.HPLC of Formula: 2387-23-7 This article mentions the following:

Some Eastern Asian countries deem pufferfish – especially its muscle – a culinary delight. Herein, mol. mass fingerprinting of soups prepared by Takifugu flavidus, Takifugu obscurus and Takifugu rubripes was established via matrix-assisted laser desorption/ionization – mass spectrometry (MALDI MS). Soup samples were directly analyzed by MALDI MS to collect mass spectra within 0-700 Da in a quick way, followed by principal component anal. to distinguish the different soups and to find out the distinctive compounds among the soups. High performance liquid chromatog. – tandem MS (HPLC-MS/MS) was applied to identify the compounds Nineteen compounds were identified from the HPLC-MS/MS data by using METLIN database. Through literature mining, we found that these compounds are closely related to the flavor, nutrition, and safety of pufferfish soups. This method can also be used as a facile way to distinguish between different pufferfish fillets when morphol. characters have been damaged or destroyed. In the experiment, the researchers used many compounds, for example, 1,3-Dicyclohexylurea (cas: 2387-23-7HPLC of Formula: 2387-23-7).
