The practice of abusing antibiotics to improve livestock growth poses a threat to food safety. To prevent and regulate this, accurate monitoring of residual veterinary drugs (VDs) is required. A method based on QuEChERS with dispersive solid-phase extraction for the determination of multi-class VDs was investigated using selected product ions under optimized multiple reaction monitoring conditions. During the clean-up procedure, chitosan, octadecyl silica, primary-secondary amine, and enhanced matrix removal (EMR)-lipid were evaluated for simultaneous anal. of multi-class VDs in beef matrix. The EMR sorbent was most advantageous (113/115) compared to others, and showed a satisfactory recovery range (70.7-117.9%) except cefquinome (67.3%) and cefalonium (69.8%). This methodol. can be used to detect oxolinic acid and ractopamine (27.4% and 88.0% of maximum residue limit, resp.) in real beef samples. We thus study propose a simple and fast anal. method for multi-class VDs for the future health of humans and animals. In the experiment, the researchers used many compounds, for example, (4R,5S,6S,7R,9R,11E,13E,15R,16R)-6-(((2R,3R,4S,5S,6R)-4-(Dimethylamino)-3,5-dihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)-16-ethyl-4-hydroxy-5,9,13-trimethyl-7-(2-(piperidin-1-yl)ethyl)-15-(piperidin-1-ylmethyl)oxacyclohexadeca-11,13-diene-2,10-dione (cas: 328898-40-4HPLC of Formula: 328898-40-4).
(4R,5S,6S,7R,9R,11E,13E,15R,16R)-6-(((2R,3R,4S,5S,6R)-4-(Dimethylamino)-3,5-dihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)-16-ethyl-4-hydroxy-5,9,13-trimethyl-7-(2-(piperidin-1-yl)ethyl)-15-(piperidin-1-ylmethyl)oxacyclohexadeca-11,13-diene-2,10-dione (cas: 328898-40-4) belongs to piperidine derivatives. The piperidine moiety constitutes an important building block for the synthesis of a variety of bioactive natural products, alkaloids and other drugs. Some chemotherapeutic agents have piperidine moiety within their structure, foremost among them, vinblastine and raloxifene.HPLC of Formula: 328898-40-4
