trait white to yellowish needle-like crystals.
Use for synthesis of antibacterial synergist trimethoprim
for synthesis of antibacterial synergist trimethoprim
for use as sulfanilamide synergist, an important intermediate of the antibacterial synergist TMP.
production method 1. From gallic acid (or tannic acid) by dimethyl sulfate methylation, esterification, and then hydrazine hydrate hydrazine reaction, and then the red blood salt oxidation system. The yield of industrial production was more than 70%. 2. From vanillin aldehyde by bromination, hydrolysis, methylation and derived. With p-nitrotoluene as raw material, by oxidation-reduction, then with sodium nitrite diazotization, hydrolysis of p-hydroxybenzaldehyde, bromination, dimethoxylation, methylation and derived. Further, 3,4, 5-trimethoxybenzaldehyde can also be prepared from trimethoxybenzonitrile and p-hydroxybenzaldehyde.
