1. It is the main spice in Hawthorn flower, sunflower and lilac flavor.
2. It is used as a fragrance agent in lily of the valley.
3. It is used as a modifier in Osmanthus fragrans.
4. It can also be used in daily flavors and food flavors.
Flavoring: Due to its sweet anise flavor, it is used as a flavoring in food. Fragrance ingredient: p-Anisaldehyde is often used in the formulation of perfumes and spices to bring sweet and floral aromas. Chemical intermediate: It is an intermediate in the synthesis of various organic compounds, including drugs, agrochemicals and dyes. Research and Development: In the laboratory, p-methoxybenzaldehyde is used in organic synthesis and as a reagent in various chemical reactions. Histological staining: It can be used for histological staining purposes, especially when examining certain types of tissues.
It is soluble in ethanol, soluble in ethyl ether, benzene and other organic solvents, also soluble in water.
Stored at a dry, shady, ventilated place.
Container: Use airtight containers made of glass or high-density polyethylene (HDPE) to prevent contamination and evaporation.
Temperature: Store in a cool and dry place, away from direct sunlight and heat sources. If long-term storage is required, it is best to store it at room temperature or in the refrigerator.
Ventilation: Make sure the storage area is well ventilated to avoid vapor accumulation.
Incompatibility: Keep away from strong oxidants and acids, as p-anisaldehyde will react with these substances.
Label: Clearly label containers with chemical name, concentration, and hazard information.
Safety Precautions: Store in accordance with local regulations and safety guidelines and ensure appropriate safety equipment is available in case of spills or leaks.
p-Anisaldehyde is generally considered to have low toxicity, but it may still pose some health risks if not handled properly. Here are some key points about its potential harm to the human body:
1.Inhalation: Exposure to p-methoxybenzaldehyde vapor can irritate the respiratory tract, causing symptoms such as coughing, sneezing or difficulty breathing.
2. Skin Contact: May cause skin irritation or allergic reaction in some people. Prolonged or repeated contact should be avoided.
3. Eye Contact: p-Anisaldehyde may irritate eyes, causing redness, tearing, or discomfort.
4. Ingestion: Ingestion of p-anisaldehyde may be harmful and may cause gastrointestinal irritation.
5. Safety Precautions: When handling terephthalaldehyde, it is recommended to use appropriate personal protective equipment (PPE) such as gloves, goggles, and lab coats, and work in a well-ventilated area or under a fume hood.
6. Regulatory Information: Always refer to the Safety Data Sheet (SDS) for terephthalaldehyde for specific information on hazards, handling, and emergency measures.
In summary, while p-anisaldehyde is not classified as acutely toxic, it still needs to be handled with care to minimize exposure and potential health risks.
1. Its gas and air form an explosive mixture. Wear protective glasses, protective clothing, and protective gloves.
2. Exist in tobacco leaves and smoke.
3. It naturally exists in essential oils such as star anise oil, cumin oil, star anise oil, dill oil, acacia oil, and corn oil.
4. It is not very stable to light, it is easy to oxidize and change color in the air to generate anisic acid.
5. p-Methoxybenzaldehyde can be used to protect diols, dithiols, amines, hydroxylamines and diamines.
Diol protection p-methoxybenzaldehyde can be easily formed by the reaction of diol and aldehyde to form acetal. The catalyst used can be hydrochloric acid or zinc chloride, or other methods such as iodine catalysis and polyaniline as the carrier Sulfuric acid catalysis, indium trichloride catalysis, bismuth nitrate catalysis, etc. P-methoxybenzaldehyde reacts with L-cysteine to obtain thiazole derivatives.
Reaction with amino groups P-methoxybenzaldehyde can react with amino groups to form Schiff bases, which are reduced by NaBH4 to form secondary amines.
Formation of ethylene oxide derivatives p-methoxybenzaldehyde can react with sulphur ylides to form ethylene oxide derivatives, and can also react with diazonium compounds to obtain such derivatives. Reaction with ethylene oxide derivatives can also expand the ring to obtain furan ring derivatives.
Diacylation reaction Under the catalysis of tetrabutylammonium bromide (TBATB), p-methoxybenzaldehyde can react with acid anhydride to form diacylation products.
In the allylation reaction, due to the strong electron donating effect of the para-methoxy group, p-methoxybenzaldehyde reacts with allyltrimethylsilane under the catalysis of bismuth trifluorosulfonate to obtain the diallylated product .
