2024/7/5
1、 Factors affecting the quality identification of di tert butyl dicarbonate
1. Appearance
High quality di tert butyl dicarbonate products should have a colorless transparent liquid or crystal appearance. If the product has a slightly yellow appearance, it indicates that the solvent content in the product is high and it is not a high-quality product.
2. Main content
This indicator is a necessary item in the product analysis form. Although there are multiple domestic suppliers, the content of this product is generally above 99%, and there are few higher quality products. The main content of di tert butyl dicarbonate produced by Shunxiang Pharmaceutical is usually higher than the value of 99.5%, which is difficult for similar production enterprises to meet.
3. Moisture content
The moisture content of high-quality di tert butyl dicarbonate should be less than about 0.01%.
4. Impurities
The lower the impurity content, the higher the purity of the product. The impurity content of di tert butyl dicarbonate supplied by excellent manufacturers is usually less than 0.019%, and high-purity di tert butyl dicarbonate has almost no other impurities.
