Aspirin

Diethyl Phthalate is an odorless, colorless, oily liquid. It is used in making plastics, insecticides, cosmetics and aspirin, and is found in toothbrushes, automobile parts, toys, tools, and food packaging.

Salicylic acid is a colorless, organic compound with the chemical formula C7H6O3, renowned for its widespread applications in skincare and medicine. It is a beta hydroxy acid (BHA) with properties that make it effective for exfoliating and treating various skin conditions. In skincare, salicylic acid is used to treat acne by unclogging pores and reducing inflammation. It is also employed for its keratolytic properties, which help remove dead skin cells, making it valuable for treating conditions like psoriasis, warts, and calluses. In medicine, salicylic acid has historically been used for pain relief and fever reduction, and it is the precursor to aspirin. Its ability to address a range of skin concerns and its medical applications underscore its significance in both personal care and healthcare fields.

Phenol is an organic compound, chemical formula C6H5OH, is a colorless needle crystal with a special smell.It's toxic, is an important raw material in the production of some resins, fungicides, preservatives and drugs (such as aspirin). It can also be used for disinfection of surgical instruments and excreta treatment, skin sterilization, itching and otitis media. Melting point 43�ºC, slightly soluble in water at room temperature, soluble in organic solvents; When the temperature is higher than 65�ºC, can be mixed with water in any proportion. Phenol is corrosive.

Phenol is an organic compound with C6H5OH. It is a colorless needle -shaped crystal with a special smell. It is toxic and is an important raw material for producing certain resins, sterilization agents, preservatives, and drugs (such as aspirin). It can also be used for the treatment of sterilized surgical equipment and excrement, skin sterilization, itching and otitis media. The melting point is 43 �° C, which is slightly soluble at water at normal temperature, and is easily soluble in organic solvents. When the temperature is higher than 65 �° C, it can solve the water in any proportion. The phenol is corrosive. After contact, the local protein degenerates. The solution can be washed with alcohol with alcohol. A small part of the phenol is exposed to the air by oxidation into pink. When the three -price iron ion becomes purple, this method is usually used to test the phenol.

Sodium Salicylate is a shiny, white powder with sweetish taste and mild aromatic aroma that is soluble in water, glycerol, and alcohol. Used in medicine and as a preservative and as an analgesic and antipyretic agent. It also acts as non-steroidal anti-inflammatory drug (NSAID) in Aspirin, and induces apoptosis in cancer cells and also necrosis. USP, or United States Pharmacopeia, grade chemicals comply with the standards of the United States Pharmacopeia and National Formulary (USP-NF). USP Grade chemicals are fit for use in food, drugs, and medicines. They are subject to stringent testing and are typically required to have the highest level of purity.

CAS : 59-05-2 Packing : 25kg/Drum Methotrexate is used as a disease-modifying treatment for some autoimmune diseases, including rheumatoid arthritis, juvenile dermatomyositis, psoriasis, psoriatic arthritis, lupus, sarcoidosis, Crohn's disease (although a recent review has raised the point that it is fairly underused in Crohn's disease), eczema and many forms of vasculitis. Although originally designed as a chemotherapy drug (using high doses), in low doses, methotrexate is a generally safe and well tolerated drug in the treatment of certain autoimmune diseases. Because of its effectiveness, low-dose methotrexate is now first-line therapy for the treatment of rheumatoid arthritis. Weekly doses are beneficial for 12 to 52 weeks duration therapy, although discontinuation rates are as high as 16% due to adverse effects. Although methotrexate for autoimmune diseases is taken in lower doses than it is for cancer, side effects such as hair loss, nausea, headaches, and skin pigmentation are still common. Use of low doses of methotrexate together with NSAIDS such as aspirin or paracetamol is relatively safe in people being treated for rheumatoid arthritis, if adequate monitoring is done. Function 1.It is used to treat cancer, autoimmune diseases, ectopic pregnancy, and for medical abortions. 2.It is used for include breast cancer, leukemia, lung cancer, lymphoma, and osteosarcoma.Types of autoimmune diseases 3.It is used for include psoriasis, rheumatoid arthritis, and Crohn's disease.
