產品簡介

Aspirin through the blood vessels in the short term can rise to alleviate the effect of a headache, the drug does to the dull pain is better than the effect of sharp pain. Therefore, the drug can relieve dull pain of mild or moderate, such as headache, toothache, neuralgia, muscle pain and dysmenorrheal. At the same time can cause the bacteria to pyrogen rise in the hypothalamus of the temperature regulating center, the set-point recovery (fell) normal levels, so also for colds, flu and antifebrile.

Structural Formula
Function	1.Induced flowering: salicylic acid is related to the induction of flowering.There are dozens of plants promoted by salicylic acid, providing a new idea for the physiological regulation of horticultural plants. 2．Promoting high quality and high yield of crops: low-concentration salicylic acid can significantly enhance anabolism, increase grain’s weight ａnd number, increased yield and improved quality. 3．Improve the resistance and tolerance of crops to adversity: most plants, including rice, corn, wheat, rape, tomato, vegetable, bean, cucumber, garlic, soybean, sugar beet and tobacco, etc., have better resistance to salt ,drought and cold after the application of salicylic acid. 4.Improve the storage of fruit: after salicylic acid treatment, the cell membrane permeability and malondialdehyde content decreased;the respiration rate decreased significantly;the fruit senescence was delayed. Similar results were observed in studies on fruits such as pear, peach and citrus. This may be related to the inhibition of ethylene production. The production of ethylene was observed by salicylic acid treatment, which proved that the inhibitory effect of salicylic acid was related to salicylic acid concentration, temperature and physiological state of potato block. 5.Salicylic acid has a certain effect on the preservation of flowers, and can significantly inhibit the growth of bacteria
Storage	It should be stored in a cool, ventilated and dry place, far away from the fire source and heat source.Keep it separate from explosive products and oxidizing agents. Avoid light.

Stability:

Stable. Keep dry. Incompatible with strong oxidizing agents, strong bases, strong acids, various other compounds such as iodides, iron salts, quinine salts, etc.

Uses:

1.Acetylsalicylic acid is the raw material for rodenticide intermediates 4-hydroxycoumarin.
2.Used to make outdoor structural members and equipment parts exposed in highlights, such as the automobile body, agricultural machinery parts, meters and electric lamps, road marking, etc.
3.It is the earliest applied, the most popular and the most common antipyretic analgesics anti-rheumatism medicine, has aspects of pharmacological effects as antipyretic-analgesic and anti-inflammatory, anti-platelet aggregation and works quickly and effectively.
