overview | 3-chloro-4-hydroxybenzaldehyde can be used as an intermediate in pharmaceutical and chemical synthesis, such as ethyl vanillin, 2-chloro-4-(morpholine methyl) phenol and ferrocenyl hydrazone compounds with electrochemical activity. |
safety instructions | if 3-chloro -4-hydroxybenzaldehyde is inhaled, please move the patient to fresh air. If the skin is in contact with the skin, remove the contaminated clothes, rinse the skin thoroughly with soapy water and clear water, and see a doctor if you feel uncomfortable. If the eyes are in contact with clear eyes, separate the eyelids and rinse with flowing water or normal saline, and seek medical treatment immediately; if ingested, gargle immediately, forbid vomiting, should seek medical treatment immediately. The advice to protect the rescuer is as follows: transfer the patient to a safe place, consult a doctor, and if conditions permit, please show the chemical safety technical specification to the doctor on site. |
