• Chemische Eigenschaften

  When freshly prepared, sodium formaldehyde sulfoxylate occurs as white, odorless crystals, which quickly develop a characteristic garlic odor on standing.

• Chemische Eigenschaften

  white solid; used as stripping and discharge agent for textiles [HAW93]

• Verwenden

  Sodium Hydroxymethanesulfinate Hydrate is the hydrated version of Sodium Hydroxymethanesulfinate (S634950), which is an organic reductant that is stable in alkaline enviroments but readily decomposes in acidic medium to produce a number of products, one of them being sulfur dioxide. Sodium hydroxymethanesulfinate is also used in conjunction with substituted anilines (e.g. p-Anisidine [A673505]) to synthesize anilinomethanesulfonates.

• Verwenden

  Pharmaceutic aid (preservative).

• Vorbereitung Methode

  Sodium formaldehyde sulfoxylate is manufactured from sodium dithionate and formaldehyde in water.

• Flammability and Explosibility

  Non flammable

• Pharmazeutische Anwendungen

  Sodium 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.

• Sicherheit(Safety)

  The 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

• Lager

  Store in well-closed, light-resistant containers at controlled room temperature (15–30℃).

• läuterung methode

  It crystallises from H2O as the dihydrate and decomposes at higher temperatures. Store it in a closed container in a cool place. It is insoluble in EtOH and Et2O and is a good reducing agent. [X-ray structure: Tuter J Chem Soc 3064 1955.] Note that this compound {HOCH2SO2Na} should not be confused with formaldehyde sodium bisulfite adduct {HOCH2SO3Na} from which it is prepared by reduction with Zn. [Beilstein 1 IV 3052.]

• Inkompatibilitäten

  Sodium formaldehyde sulfoxylate is incompatible with strong oxidizing agents; it is decomposed by dilute acid.

• Regulatory Status

  Included 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.
