Sodium Ascorbate USP Grade Specifications:
C6H7NaO6 198.11
l-Ascorbic acid, monosodium salt;
Monosodium l-ascorbate CAS 134-03-2

DEFINITION
Sodium Ascorbate contains NLT 99.0% and NMT 101.0% of sodium ascorbate (C6H7NaO6), calculated on the dried basis.

IDENTIFICATION
A. Infrared Absorption
B. Reducing capacity
Sample solution: 20 mg/mL
Analysis: Add 1 mL of 0.1 N hydrochloric acid to 4 mL of the Sample solution and add alkaline cupric tartrate.
Acceptance criteria: The solution reduces alkaline cupric tartrate slowly at room temperature, but more readily upon heating.
C. Identification Tests—General, Sodium: A 20-mg/mL solution meets the requirements.

Optical Rotation, Specific Rotation:
Sample solution: 100 mg/mL in carbon dioxide-free water. Use the solution immediately after preparation.
Acceptance criteria: +103° to +108°
pH:
Sample solution: 100-mg/mL solution
Acceptance criteria: 7.0 to 8.0
Loss on Drying: Dry a sample in a suitable vacuum drying tube, using phosphorus pentoxide as the desiccant, at 60° for 4 h: it loses NMT 0.25% of its weight.
Packaging and Storage: Preserve in tight, light-resistant containers.

Specifications of Sodium Ascorbate BP Ph Eur Grade:
C6H7NaO6 --- 198.1 --- CAS 134-03-2

pH: 7.0 to 8.0 determined on freshly prepared solution S.
Sulfates: Maximum 150& ppm.
Copper: Maximum 5 ppm.
Iron: Maximum 2 ppm.
Nickel: Maximum 1 ppm.
Loss on drying: Maximum 0.25 per cent, determined on 1 g by drying in an oven at 105C.

Specifications of Sodium Ascorbate FCC Food Grade:
Vitamin C Sodium; Sodium L-Ascorbate
C6H7NaO6 Formula weight 198.11
INS: 301 CAS: 134-03-2

DESCRIPTION
Sodium Ascorbate occurs as a white to yellow, crystalline powder that does not darken on exposure to light. One gram is soluble in 2 mL of water. The pH of a 1:10 aqueous solution is about 7.5.
Function: Antioxidant; meat curing aid; nutrient.

REQUIREMENTS
Identification:
A. A 1:50 aqueous solution slowly reduces alkaline cupric tartrate at 25C, and does so more readily upon heating.
B. Add 4 drops of methylene blue to 2 mL of a 1:50 aqueous solution acidified with 0.5 mL of 0.1 N hydrochloric acid, and warm to 40C. The deep blue color disappears almost completely within 3 minutes.
C. Dissolve 15 mg of sample in 15 mL of a 1:20 trichloroacetic acid:water solution, add about 200 mg of activated charcoal, shake vigorously for 1 minute, and filter through a small fluted filter, returning the filtrate, if necessary, until clear. Add 1 drop of pyrrole to 5 mL of the filtrate, agitate gently until dissolved, and then heat in a water bath at 50C. A blue color appears.
D. A sample gives positive tests for Sodium.
Assay: Not less than 99.0% and not more than 101.0% of C6H7NaO6 after drying.
Lead: Not more than 2 mg/kg.
Loss on Drying: Not more than 0.25%.
Optical (Specific) Rotation [α]D25C: Between +103° and +108°.

Specifications of Sodium Erythorbate FCC Food Grade:
C6H7NaO6-H2O Formula weight 216.12
CAS Number 6381-77-7

DESCRIPTION
Sodium Erythorbate occurs as a white, crystalline powder or as granules. In the dry state it is reasonably stable in air, but in solution it deteriorates in the presence of air, trace metals, heat, and light. One-gram dissolves in about 7 mL of water. The pH of a 1:20 aqueous solution is between 5.5 and 8.0.
Function: Preservative; antioxidant.

REQUIREMENTS
Identification:
A. A 1:50 aqueous solution slowly reduces alkaline cupric tartrate at 25C but does so more readily upon heating.
B. Add a few drops of sodium nitroferricyanide, followed by 1 mL of 0.1N sodium hydroxide to 2 mL of a 1:50 aqueous solution acidified with 0.5 mL of 0.1N hydrochloric acid. A transient blue color immediately appears.
C. It gives positive tests for Sodium.
Assay: Not less than 98.0% and not more than 100.5% of C6H7NaO6-H2O.
Lead: Not more than 5 mg/kg.
Loss on Drying: Not more than 0.25%.
Optical (Specific) Rotation [alpha]D 25°: Between +95.5° and +98.0°.
Oxalate: Passes test.
