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, 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3Recommanded Product: 1220-83-3).
4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3) belongs to pyrimidine derivatives. Pyrimidine is an aromatic heterocyclic organic compound similar to pyridine. Pyrimidine derivatives also play an important role in drug development, either in concert with other compounds or on their own.Recommanded Product: 1220-83-3
