Description
Sodium ascorbate is the sodium salt of ascorbic acid, commonly known as vitamin C. It is a white or slightly yellow-colored, practically odorless, crystalline powder with a pleasant saline taste. Sodium ascorbate is approved for use as a food additive in many countries and is a combination of sodium and vitamin C, serving as an antioxidant and an acidity regulator in pharmaceutical manufacturing and the food industry. It provides both sodium and vitamin C for the human body, which is effective in preventing or treating vitamin C deficiency. Studies have shown that taking sodium ascorbate is helpful for cancer prevention and treatment.
Uses
Used in Pharmaceutical Manufacturing:
Sodium ascorbate is used as an antioxidant and acidity regulator in pharmaceutical manufacturing. It helps to prevent the oxidation of sensitive compounds and maintains a stable pH level in the production process.
Used in the Food Industry:
Sodium ascorbate is used as an antioxidant and acidity regulator in the food industry. It helps to prevent the oxidation of food components, maintaining freshness and extending the shelf life of various products.
Used in Cell Culture:
Sodium ascorbate is used as a reducing agent in cell culture applications, helping to reduce oxidative stress and maintain a healthy environment for cell growth.
Used as an Antimicrobial and Antioxidant in Foodstuffs:
Sodium ascorbate is used to inhibit the growth of microorganisms and prevent oxidation in various food products, enhancing their quality and safety.
Used in Cancer Prevention and Treatment:
Studies have shown that taking sodium ascorbate is helpful for cancer prevention and treatment, making it a valuable supplement for those at risk or undergoing cancer treatment.
Used in Vitamin C Supplementation:
As a vitamin C supplement, sodium ascorbate provides both sodium and vitamin C for the human body, which is effective in preventing or treating vitamin C deficiency and may be easier to tolerate for individuals with sensitive digestive systems.
Used in Flour Treatment:
Sodium ascorbate is used as a flour treatment agent, improving the quality and texture of baked goods.
Used as a Coenzyme, Plant Metabolite, Human Metabolite, and Reducing Agent:
Sodium ascorbate has various roles in biological systems, including acting as a coenzyme, plant metabolite, human metabolite, Daphnia magna metabolite, and reducing agent.

Production Methods
An equivalent amount of sodium bicarbonate is added to a solution
of ascorbic acid in water. Following the cessation of effervescence,
the addition of propan-2-ol precipitates sodium ascorbate.
Air & Water Reactions
Water soluble. Aqueous solutions are subject to quick air oxidation at pH greater than 6.0.
Reactivity Profile
A weak base. Materials in this group are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.
Health Hazard
SYMPTOMS: Ingestion of 10 grams or more of this type of compound may cause diarrhea.
Fire Hazard
Flash point data for Sodium ascorbate are not available. Sodium ascorbate is probably combustible.
Flammability and Explosibility
Notclassified
Pharmaceutical Applications
Sodium ascorbate is used as an antioxidant in pharmaceutical
formulations, and also in food products where it increases the
effectiveness of sodium nitrite against growth of Listeria monocytogenes
in cooked meats. It improves gel cohesiveness and sensory
firmness of fiberized products regardless of vacuum treatment.
It is also used therapeutically as a source of vitamin C in tablets
and parenteral preparations.
Biochem/physiol Actions
Ascorbic acid exhibits anti-oxidant properties. It is a primary substrate for detoxifying hydrogen peroxide. Ascorbic acid is a co-factor for the synthesis of adrenal steroids and catecholamines. L-Ascorbic acid (Vitamin C) is a water soluble molecule used in a wide variety of applications, including cell culture, as a reducing agent that helps reduce oxidative stress. L-Ascorbate can be regenerated by biological systems.
Safety Profile
Human mutation data
reported. When heated to decomposition it
emits toxic fumes of Na2O.
Safety
The parenteral administration of 0.25-1.00 g of sodium ascorbate,
given daily in divided doses, is recommended in the treatment of
vitamin C deficiencies. Various adverse reactions have been
reported following the administration of 1 g or more of sodium
ascorbate, although ascorbic acid and sodium ascorbate are usually
well tolerated; see Ascorbic acid. There have been no reports of
adverse effects associated with the much lower concentrations of
sodium ascorbate and ascorbic acid, which are employed as
antioxidants.
The WHO has set an acceptable daily intake of ascorbic acid,
potassium ascorbate, and sodium ascorbate, as antioxidants in
food, at up to 15 mg/kg body-weight in addition to that naturally
present in food.
storage
Sodium ascorbate is relatively stable in air, although it gradually
darkens on exposure to light. Aqueous solutions are unstable and
subject to rapid oxidation in air at pH > 6.0.
The bulk material should be stored in a well-closed nonmetallic
container, protected from light, in a cool, dry place.
Incompatibilities
Incompatible with oxidizing agents, heavy metal ions, especially
copper and iron, methenamine, sodium nitrite, sodium salicylate,
and theobromine salicylate. The aqueous solution is reported to be
incompatible with stainless steel filters.
Regulatory Status
GRAS listed. Accepted for use as a food additive in Europe.
Included in the FDA Inactive Ingredients Database (IV preparations;
oral tablets). Included in nonparenteral and parenteral
medicines licensed in the UK. Included in the Canadian List of
Acceptable Non-medicinal Ingredients.
Check Digit Verification of cas no
The CAS Registry Mumber 134-03-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134-03:
(5*1)+(4*3)+(3*4)+(2*0)+(1*3)=32
32 % 10 = 2
So 134-03-2 is a valid CAS Registry Number.
