(R)-2-METHYLSUCCINIC ACID 4-TERT-BUTYL ESTER is an organic compound commonly abbreviated as TMSA. The following is an introduction to its nature, use, preparation and safety information:
Nature:
(R)-2-METHYLSUCCINIC ACID 4-TERT-BUTYL ESTER is a colorless liquid with good solubility in water and most organic solvents. Its molecular formula is C9H16O4 and its molecular weight is 188.22g/mol. It has a density of about 0.995 g/mL and a boiling point of about 198-200 ° C.
Use:
(R)-2-METHYLSUCCINIC ACID 4-TERT-BUTYL ESTER is a commonly used organic synthesis intermediate. It can be used as a substrate, reducing agent and ligand for chiral catalysts. In addition, it can also be used to prepare organic compounds such as drugs, fragrances and dyes.
Method: The preparation of
(R)-2-METHYLSUCCINIC ACID 4-TERT-BUTYL ESTER usually involves specific synthetic routes and chemical reactions. A common synthetic method is to obtain (R)-2-methyl-3-methylthiopropionate by oxidation of methyl propyl mercaptan (MPTS), followed by methyl esterification with acetic anhydride to obtain the desired product. Specific synthesis steps and conditions can be adjusted according to needs and experimental conditions.
Safety Information:
(R)-2-METHYLSUCCINIC ACID 4-TERT-BUTYL ESTER is a chemical, so you need to pay attention to safety when using and handling it. It is combustible and should be kept away from fire and flame. Wear protective gloves, goggles and protective clothing during operation. Avoid contact with skin, eyes and respiratory tract. In case of accidental contact, rinse immediately with water and seek medical assistance. In addition, it should be kept away from children and animals, stored in sealed containers, and placed in a cool, dry place.

Physical and Chemical Properties |
Colourless liquid with pleasant odour, used as chemical intermediate, solvent and extraction agent. |
Use | Uses compared with cis-l, 2-dichloroethylene, trans -1, 2-dichloroethylene has less toxicity and more active chemical properties, in the industry, it is mainly used in the extraction of heat sensitive substances or solvents of certain polymer materials and raw materials for organic synthesis. A solvent such as fat, phenol, and camphor. Dyes, fragrances, paints, thermoplastics. Degreasing agent. |
It has a similar chloroform smell. The vapor forms an explosive mixture with air. Heat decomposes toxic gases such as phosgene and hydrogen chloride.
properties
Anti -1, 2-dichloroethylene is a chemical, colorless and slightly irritating volatile liquid, flammable, and its vapor and air can form an explosive mixture. Combustion and explosion caused by open flame and high heat energy. In the air, it decomposes and releases highly toxic phosgene and hydrogen chloride gas. It can react strongly with oxidants. It is possible to produce explosive chloroacetylene with copper and its alloys.
health hazards
Inhalation of high doses of 1,2-dichloroethylene can cause nausea, drowsiness and fatigue, while inhalation of extremely high doses can even cause death. When animals inhale high doses of trans -1, 2-dichloroethylene for a short or long time, their liver and lungs will be damaged, and longer exposure will have more serious effects. Inhaling very high doses of trans -1, 2-dichloroethylene can also destroy the animal's heart. Ingestion of very high doses of cis or trans 1, 2-dichloroethylene can even die. Lower concentrations of cis -1, 2-dichloroethylene will affect the blood. If the number of red blood cells is reduced, it will also affect the liver.
Toxicity
The toxicity to humans is similar to chloroform. The maximum allowable concentration of human in the air is 100ppm. When the air contains 100ppm, it can smell the smell of aromatic fruits. If the contact time is short, it can cause mild poisoning. The symptoms are dizziness, fatigue or cramps of limbs, nausea and vomiting.
Long-term inhalation at low concentration or exposure at high concentration (5000ppm) for 30 minutes can cause severe poisoning. The symptoms are severe vomiting, severe diarrhea, bleeding in the stomach, intestines, lungs and chest cavity, reduced heart rhythm, increased body temperature, from spasm to rest, loss of consciousness or death.
Skin contact with poison gas can cause skin burns. Treatment, such as skin burns, can be washed with warm water or warm soapy water.
Those with severe poisoning should be transferred to fresh air first, and their collars and belts should be loosened. If breathing stops, artificial respiration should be applied until the poisoned person can breathe naturally, and they should be sent to the hospital for treatment immediately.
