For all users of di-tert-butyl dicarbonate, how to identify the quality of the product after receiving the goods is a difficult problem. To identify high-quality di-tert-butyl dicarbonate, we should start with the following conveniences:
1. Appearance: The appearance of high-quality di-tert-butyl dicarbonate products should be colorless and transparent liquid or crystals. If the appearance of the product is slightly yellow, it means that the product has a high solvent content and is not a high-quality product.
2. Main content; this indicator is a necessary item of the product analysis sheet. Although there are many domestic suppliers of this product, the content is generally above 99%, and there are few better products. The main content of di-tert-butyl dicarbonate produced by Jinjing Chemical is usually higher than 99.5%. It is difficult for similar manufacturers to meet this standard.
