Chloramphenicol-d5

Chloramphenicol residues in food of animal origin are monitored closely, and quantitative results depend on a labelled internal standard added before sample preparation begins. Chloramphenicol-d5 provides five deuterium atoms on the aromatic ring, giving formula C11H7D5Cl2N2O5 and molecular weight 328.16, and it appears as an off-white solid. Laboratories use it to correct recovery and matrix effects in LC-MS/MS or GC-MS/MS residue methods, to support method validation and confirmation of identity, and to keep calibration stable across long analytical sequences. Pack sizes available for this item range from 100 ug to 100 mg, including 1 mg, 5 mg, 10 mg, 25 mg and 50 mg. Store at -20 +/- 5 C and ship with ice packs. Enquiries about quotations, specifications or related documents are welcome.
