Method:
The synthesis method of methyl 2,4-dihydroxy-3,6-dimethylbenzoate is as follows:
3,6-dimethylbenzyl alcohol is reacted with chloroformic acid to generate 2,4-dihydroxy-3,6-dimethylbenzoic acid under alkaline conditions.
Then, 2,4-dihydroxy-3,6-dimethylbenzoic acid is reacted with formic anhydride to generate methyl 2,4-dihydroxy-3,6-dimethylbenzoate.
Safety Information:
Caffeine has a central nervous system stimulating effect, and excessive intake may cause uncomfortable symptoms such as nervous system irritation, insomnia, heart palpitations, and restlessness.
Long-term excessive caffeine intake may lead to dependence and withdrawal symptoms.
