Usage
1. This product is an intermediate of medicine, perfume and liquid crystal. P-hydroxybenzaldehyde is used in the production of antibacterial synergists TMP (trimethoprim), amoxicillin, amoxicillin, artificial gastrodia elata, rhododendron, bezafibrate, esmolol; used in the production of spices Anisaldehyde, vanillin, ethyl vanillin, raspberry ketone.
2. The key raw material for the production of p-hydroxybenzoyl acid (p-hydroxyphenylglycine is a key intermediate in the new generation of semi-synthetic penicillium amoxicillin). At the same time, it is also the key intermediate raw material for the production of pesticide-bromobenzonitrile.
