Application:
Hazard Symbols Xi - Irritant Risk Codes 36/37/38 - Irritating to eyes, respiratory system and skin. Safety Description S26 - In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. S36 - Wear suitable protective clothing. S37/39 - Wear suitable gloves and eye/face protection WGK Germany 3 TSCA Yes HS Code 2917361900 Hazard Class IRRITANTmono-Methyl Terephthalate (MMT) (CAS: 1679-64-7) is a kind of phthalate ester. It can be obtained during the hydrolytical transformation process of dimethyl terephthalate (DMT) by some microbes such as Rhodococcus rubber and Pasteurella multocida. It is also the intermediate during the manufacturing of dimethyl terephthalate, terephthalic acid and some other derivatives. As the ester form of terephthalate, it is widely used for the manufacturing of plastics, paints, synthetic fibers and polyester. mono-Methyl Terephthalate is used in the synthesis of Hepatits C antiviral activity. Also used in the design and preparation of benzamide derivatives as BRAFV600E inhibitors, which if mutated, can influence malignancies and melanomas.Preparation Method:
Dimethyl terephthalate is used as raw material, hydrolyzed in KOH methanol solution, and then acidified with hydrochloric acid to prepare monomethyl terephthalate, with a product yield of 91.2%.
