Chemische Eigenschaften
White solid
Verwenden
Sodium thioglycolate has been used:
- as a growth supplement in enrichment media and to study its effect on Arcobacter
- in influenza hemagglutinin formulation in order to reduce disulfide-mediated cross-linking and early potency loss
- in electron microscopy
Definition
The sodium salt of thioglycolic acid.
Allgemeine Beschreibung
White powder with a slight odor. Used in cold-waving of hair and as a dipilatory.
Air & Water Reaktionen
Hygroscopic. Discolors on exposure to air. Water soluble.
Reaktivität anzeigen
Sodium thioglycolate is hygroscopic and sensitive to air. Discolors if exposed to iron . May generate flammable and toxic hydrogen sulfide with strong reducing agents.
Hazard
Yields toxic hydrogen sulfide on decompo-
sition, may be toxic by skin absorption.
Brandgefahr
Flash point data for Sodium thioglycolate are not available. Sodium thioglycolate is probably combustible.
Sicherheitsprofil
Poison by intravenous and intraperitoneal routes. Moderately toxic by ingestion. A human skin irritant. This material yields hydrogen sulfide on decomposition. A death has been attributed to the absorption of toxic decomposition products from the use of this material in a hair permanent-waving solution. When heated to decomposition it emits toxic fumes of SOx and Na2O. See also SULFIDES and MERCAPTANS.
läuterung methode
It crystallises from 60% EtOH (charcoal). It is hygroscopic.[Beilstein 3 IV 600.]
