In stock
The prefix in ent-Thiamphenicol-d3 identifies the enantiomer of thiamphenicol, the mirror-image form of this widely used amphenicol antibacterial, carrying three deuterium labels. Chirality matters in residue and pharmaceutical analysis because the two enantiomers can differ in activity and in chromatographic retention, so laboratories working with chiral separation need each form on its own. This material supports method development on chiral columns, peak-identity confirmation in LC-MS/MS residue screening, and mass-spectrometric quantification in which a labelled form tracks the analyte through sample preparation. It is a white to off-white solid of formula C12H12D3Cl2NO5S and molecular weight 359.24, listed in pack sizes from 1 mg to 100 mg. Store at -20 +/- 5 C and ship with ice packs.
