四环素-d6

Tetracycline-d6 (CAS 2373374-42-4) is the hexadeuterated analog of the broad-spectrum antibiotic tetracycline, in which both methyl groups of the dimethylamino moiety are replaced by trideuteromethyl (CD3) groups (C22H18D6N2O8, MW 450.47). Tetracycline, produced by Streptomyces species, inhibits bacterial protein synthesis and exhibits activity against a wide range of Gram-positive and Gram-negative bacteria, as well as chlamydiae, mycoplasmas, and rickettsiae. Tetracycline-d6 is intended for use as a stable-isotope-labeled internal standard for the quantitative determination of tetracycline by NMR, GC-MS, or LC-MS, supporting pharmacokinetic, bioanalytical, food-safety, and antibiotic residue analysis studies.
