General description

Efficacy of 2.5% sodium hypochlorite (NaOCl) solution as endodontic irrigant has been tested. It was reported as comparatively more efficient antimicrobial agent than 0.2% chlorhexidine gluconate solution. It has been proposed as tissue solvent. It has bactericidal properties. Effect of time and storage conditions on tissue-dissolving capacity of various concentrations of NaOCl have been evaluated. NaOCl is commonly used for the removal of bloom-forming or biofouling organisms. It has been proposed as algicidal agent.

Application

Sodium hypochlorite is an oxidant used with catalytic TEMPO for oxidation of alcohols. It is generally used in the synthesis of sodium 3,3′-bis(sulfonato)-4,4′-bis(acetamido)azobenzene.

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. What is the definition of available chlorine?

    Available chlorine is a measure of the bleaching power of a substance. Available chlorine is defined as chlorine capable of releasing an equivalent amount of atomic oxygen according to the following reaction equations.Cl2 + 2OH- --> OCl- + Cl- + H2O  (eqn. 1) HOCl --> HCl + ½ O2  (eqn. 2)

  6. How is available chlorine tested?

    To analyze for available chlorine, a sample of sodium hypochlorite is added to a solution of potassium iodide in the presence of acid to liberate iodine.  The liberated iodine is titrated with standardized sodium thiosulfate.
