Florfenicol

2,2-Dichloro-N-[(1R,2S)-1,3-dihydroxy-1-(4-methylsulfonylphenyl)propan-2-yl]acetamide · CAS 73231-34-2

Veterinary USP / Veterinary grade / CP CoA per batchSDSUSDMF Type IVChloramphenicol-free statement

Florfenicol is the chloramphenicol alternative for aquaculture and livestock, and buyers need proof that chloramphenicol itself is absent — a carry-over claim that has to be substantiated by method, not by assertion. We supply a chloramphenicol-free statement with the analytical method cited.

Aquafeed customers usually require a specific particle size for premix uniformity. Micronised grade with a D90 under 50 µm is available against an agreed specification.
