Introductions of Syringaldehyde:
Syringaldehyde and 3,4,5-trimethoxybenzaldehyde are general pharmaceutical intermediates. Their main use is to synthesize the classical antibacterial agent trimethoprim. The annual global production is about 5000 tons. China is the main producer. At present, the production route of syringaldehyde and 3,4,5-trimethoxybenzaldehyde is to prepare dibromaldehyde by p-cresol tetrabromination hydrolysis, syringaldehyde by dibromaldehyde methoxylation, and 3,4,5-trimethoxybenzaldehyde by methylation.
