Specification for Erythritol

Erythritol (CAS Number: 149-32-6#) is heat stable and nonhygroscopic, soluble in water, pyridine and slightly soluble in alcohol.

Formula: C₄H₁₀O₄
Formula Weight: 122.12
Appearance: Crystalline powder
Colour: White
Odour: Odourless

Chemical Tests:

Identification: The retention time of the major peak in the HPLC chromatogram of the Assay Solution corresponds to that in the chromatogram of the Standard Solution obtained in the Assay.
Melting Range: 119 to 123°C
Assay: Not less than 99%
Ribitol plus Glycerol: Not more than 0.1%
Heavy Metals (as Pb): Not more than 5 mg/kg
Lead: Not more than 1 mg/kg
Reducing Sugars: Not more than 0.3%.
(as glucose): Not more than 0.1%.
Residue on Ignition: Not more than 0.2% after drying in a vacuum desiccator at 70°C for 6 hours.
Loss on Drying:
Assay: Use deionised water.
Mobile Phase:
Standard Solution: Transfer about 2 g of primary standard, previously dried in a vacuum desiccator at 70°C for 6 hours and accurately weigh (W), into a 50-mL volumetric flask, dilute to volume with deionised water.
Assay Solution: Prepare as directed for Standard Solution, using about 2 g of the sample (w).
Chromatographic Use a high-pressure liquid chromatograph fitted with a differential refractive index detector and a column packed with a strong cation exchange resin in the hydrogen form operated at a column temperature of 60°C, at a flow rate of approximately 0.5 mL/min.
System:
Procedure: Chromatograph triplicate 30-μL portions of the Standard Solution and record the mean of the erythritol peak areas as A. In a similar manner, chromatograph triplicate 30-μL portions of the Assay Solution and record the mean of the erythritol peak areas as a. Calculate the percentage of erythritol in the sample by the formula: % Erythritol = 100(W/w)(a/A).
