Sodium formaldehydesulfoxylate dihydrate Usage And Synthesis
Chemical PropertiesWhen freshly prepared, sodium formaldehyde sulfoxylate occurs as white, odorless crystals, which quickly develop a characteristic garlic odor on standing.
Chemical Propertieswhite crystalline powder
UsesSodium hydroxymethanesulfinate dihydrate is a versatile reagent that can be used for a wide range of organic transformations such as:
  • A SO2-2anion source for the preparation of sulfones and sultines.
  • Debromination of vicinal dibromoalkanes.
  • Reductive dehalogenation of aldehydes and ketones.

UsesPharmaceutic aid (preservative).
Production MethodsSodium formaldehyde sulfoxylate is manufactured from sodium dithionate and formaldehyde in water.
General DescriptionOxidation reation of hydroxymethanesulfinic acid with chlorite has been studied in the pH range 4-8. It is a sulfur-containing reducing agent.
Pharmaceutical ApplicationsSodium formaldehyde sulfoxylate is a water-soluble antioxidant and is generally used as the dihydrate. It is used in the formulation of injection products at a level of up to 0.1% w/v in the final preparation administered to the patient.
SafetyThe toxicological properties of sodium formaldehyde sulfoxylate have not been fully investigated. However, it is used in the formulation of injection products at a level to 0.1% w/v in the final preparation administered to the patient.
Sodium formaldehyde sulfoxylate is moderately toxic by ingestion, and when heated to decomposition it emits toxic fumes of sulfur dioxide and sodium oxide.
LD50 (mouse, oral): 4 g/kg
LD50 (rat, IP): >2 g/kg
LD50 (rat, oral): >2 g/kg
storageStore in well-closed, light-resistant containers at controlled room temperature (15–30℃).
IncompatibilitiesSodium formaldehyde sulfoxylate is incompatible with strong oxidizing agents; it is decomposed by dilute acid.
Regulatory StatusIncluded in the FDA Inactive Ingredients Database (parenteral products up to 0.1% via the IM, IV, and SC routes). Included in the Canadian List of Acceptable Non-medicinal Ingredients.
