5-Bromothiazol-2-amine(cas: 3034-22-8) belongs to anime. Nitrous acid converts secondary amines (aliphatic or aromatic) to N-nitroso compounds (nitrosamines): R2NH + HNO2 → R2N―NO. Some nitrosamines are potent cancer-inducing substances, and their possible formation is a serious consideration when nitrites, which are salts of nitrous acid, are present in foods or pharmaceutical preparations. Tertiary amines give rise to nitrosamines more slowly; an alkyl group is eliminated as an aldehyde or ketone, along with nitrous oxide, N2O.Safety of 5-Bromothiazol-2-amine

《In vitro bioaccessibility and activity of Greek oregano (Origanum vulgare L. ssp. hirtum (link) Ietswaart) compounds as affected by nitrogen fertilization》 was written by Seczyk, Lukasz; Krol, Beata; Kolodziej, Barbara. Related Products of 30931-67-0 And the article was included in Journal of the Science of Food and Agriculture on April 30 ,2020. The article conveys some information:

Greek oregano is a culinary and medicinal herb native to the Mediterranean region; however nowadays it is cultivated in many regions all over the world. It is commonly used as a spice for flavoring food products and in various traditional medicine applications. This study investigated the effect of nitrogen fertilization at 0-150 kg N ha-1 on the potential bioaccessibility and activity of Greek oregano compounds For this purpose the total phenolic content, rosmarinic acid content, and antioxidant activities of the raw material, as well as digested fractions, were determined Nitrogen fertilization had a neg. influence on the phenolic content and antioxidant activity of raw material; however, its effect on the potential bioaccessibility varied depending on the dose. The highest potential bioaccessibility and activity was determined for plants fertilized with 30 kg N ha-1. For the gastric and intestinal phases of digestion, the potential bioaccessibility percentages were 39.5% and 29.6% for total phenolics, 53.1% and 11.2% for rosmarinic acid content, 45.2% and 44.4% for antiradical activity against 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), 39.2% and 27.2% for antiradical activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 50.2% and 23.4% for reducing power, resp. The results showed that nitrogen fertilization is an important factor determining the in vitro bioaccessibility of Greek oregano compounds Furthermore, the nutraceutical potential of herbs, in term of the bioaccessibility of bioactive compounds, may be optimized during plant cultivation by applying an accurate nitrogen level.

《Adsorption of caffeic acid on chitosan powder》 was written by Liudvinaviciute, Dovile; Rutkaite, Ramune; Bendoraitiene, Joana; Klimaviciute, Rima; Zambzickaite, Greta. HPLC of Formula: 30931-67-0 And the article was included in Polymer Bulletin (Heidelberg, Germany) on April 30 ,2021. The article conveys some information:

Abstract: Adsorption of caffeic acid (CA) on chitosan (CH) powder from aqueous solution has been investigated to obtain insoluble CA-CH complex powders having different amount of CA. The pseudo-second kinetic model and the Langmuir, Freundlich and Dubinin-Radushkevich adsorption models were used to describe the kinetic and equilibrium adsorption of CA on CH. With the increase of adsorption temperature, the rate of adsorption increased while the amount of adsorbed CA decreased. The Langmuir adsorption model predicted that adsorption of CA takes place on the ionized amino groups of CH. However, with the increase of adsorption temperature the ion-exchange between carboxylic groups of CA and amino groups of CH became moderately difficult. The thermodn. characteristics of adsorption have been evaluated. CA-CH complex formation was confirmed by FT-IR spectroscopy. With increasing amount of adsorbed CA the CA-CH powder was becoming more hydrophobic. 2,2′-Azinobis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS) assay confirmed that CA retained the antioxidant activity when immobilized on chitosan power. In the experiment, the researchers used ABTS Diammonium(cas: 30931-67-0HPLC of Formula: 30931-67-0)
