Analysis Note

Assay (iodometric): ≥ 95.0 %
Density (d 20 °C/ 4 °C): 1.325 - 1.335
Identity (IR): passes test
The assay stated on the certificate of analysis refers to the date of examination. A gradual substance-specific content reduction, especially at higher temperatures, must be expected. The average content reduction at the required storage temperature of +2°c to +8°C is about 1% per month.
