111-90-0, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 111-90-0, name is Diethylene Glycol Monoethyl Ether. This compound has unique chemical properties. The synthetic route is as follows.
The 6-amino-7-methoxy-4-[3-methyl-4-(2-pyridylmethoxy)anilino]-quinazoline used as a starting material was obtained as follows: A mixture of 4-chloroanthranilic acid (17.2 g) and formamide (10 ml) was stirred and heated to 130 C. for 45 minutes and to 175 C. for 75 minutes. The mixture was allowed to cool to approximately 100 C. and 2-(2-ethoxyethoxy)ethanol (50 ml) was added. The solution so formed was poured into a mixture (250 ml) of ice and water. The precipitate was isolated, washed with water and dried. There was thus obtained 7-chloroquinazolin-4-one (15.3 g, 85%).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 111-90-0, Diethylene Glycol Monoethyl Ether.
