General description

2,3-Butanedione Monoxime (BDM) is also known as diacetyl monoxime, it is also a nucleophilic agent and it can dephosphorylates acetylcholinesterase poisoned with organophosphates. It is also a well-characterized, non-competitive inhibitor of skeletal muscle myosin-II, where it inhibits the chemical and motile activity.

Analysis Note

Solubility:
0.5 g are completely soluble and give a clear solution in 10 mL water or also in 10 mL ethanol.
Sensitivity test:
0.05 mg urea in 3 mL water and 5 mL conc. HCl together with a 3% solution in water of diacetylmonoxime heated on a water bath for 10 minutes give a light yellow color.

Other Notes

Reagent for the colorimetric determination of urea and ureido-compounds; Spectrometric reagent for Co(II), Ni(II), Pd(II) and Re(VII); Reagent for the gravimetric determination of Ni(II)
