Ceftriaxone sodium

Ceftriaxone sodium hydrolysate can be oxidized with potassium permangenate and an acid like phosphoric acid.
You can check this reference for details on how to detect oxidized Ceftriaxone sodium.

  Based on the chemiluminescence (CL) emission generated from the oxidation of ceftriaxone sodium alkali hydrolysate by potassium permanganate in polyphosphoric acid (PPA), a novel determination method for ceftriaxone sodium was developed by using a flow-injection technique. The calibration curve appears to be linear in the range between 0.05 and 100 µg mL-1 with a detection limit (3 σ) of 25 ng mL-1, and a relative standard deviation (RSD) of 0.6% for eleven replicate determinations of 5.0 µg mL-1 ceftriaxone sodium. The proposed method has been successfully utilized for the determination of ceftriaxone sodium in pharmaceutical formulations, while the chemiluminescence reaction mechanisms were investigated.
