This product is made from chondroitin sulfate (CS) polymer by digestion with Chondroitinase ABC (CAS: 9024-13-9) or Chondroitinase AC-II (CAS: 9047-57-8), and purified by the column chromatography. ΔDi-0S has a double bond (unsaturated bond) between C-4 and C-5 position of uronic acid at the non-reducing end, and “Δ (Delta)” of ΔDi-0S means the unsaturated bond. The structure of ΔDi-0S sodium salt is shown in the chart below. This product is useful as a standard for a constituent analysis of CS using a HPLC after the digestion with Chondroitinase derived from bacteria1). The enclosed Certification of Analysis lists actual content and purity for product specifications.
