CAS 141-82-2 refers to a well - known chemical compound, and in this blog, we'll delve deep into its chemical name, properties, applications, and more. As a trusted supplier of CAS 141 - 82 - 2, I'm excited to share comprehensive knowledge about this compound with you.
Chemical Name of CAS 141 - 82 - 2
The chemical name of CAS 141 - 82 - 2 is Malonic acid. Malonic acid, with the molecular formula C₃H₄O₄, is a dicarboxylic acid. Its structure consists of a central carbon atom bonded to two carboxyl groups (-COOH) and two hydrogen atoms. The IUPAC (International Union of Pure and Applied Chemistry) name for malonic acid is propanedioic acid, which precisely reflects its chemical structure as a three - carbon chain with two carboxylic acid functional groups at each end.
Properties of Malonic Acid
- Physical Properties: Malonic acid is a white crystalline solid at room temperature. It has a melting point of around 135 - 137 °C and is soluble in water, ethanol, and ether. Its solubility in water is due to the ability of the carboxyl groups to form hydrogen bonds with water molecules.
- Chemical Properties: Malonic acid is a relatively strong organic acid. It can react with bases to form salts, known as malonates. For example, when malonic acid reacts with sodium hydroxide (NaOH), it forms sodium malonate and water. Malonic acid can also undergo decarboxylation reactions under certain conditions, losing a carbon dioxide molecule to form acetic acid.
Synthesis of Malonic Acid
There are several methods for synthesizing malonic acid. One common method involves the hydrolysis of diethyl malonate. Diethyl malonate is first prepared by the reaction of chloroacetic acid with sodium cyanide to form sodium cyanoacetate, which is then esterified with ethanol to produce diethyl malonate. Diethyl malonate is then hydrolyzed with a strong base such as sodium hydroxide, followed by acidification to yield malonic acid.
Applications of Malonic Acid
- Pharmaceutical Industry: Malonic acid and its derivatives are widely used in the pharmaceutical industry. They serve as important intermediates in the synthesis of various drugs. For example, some anti - inflammatory drugs and antimalarial drugs are synthesized using malonic acid as a starting material.
- Organic Synthesis: In organic chemistry, malonic acid is a key reagent for the synthesis of a variety of organic compounds. It can be used in the synthesis of esters, amides, and other carboxylic acid derivatives. Malonic acid is also used in the synthesis of heterocyclic compounds, which have important applications in the fields of medicine, agriculture, and materials science.
- Food Industry: Malonic acid can be used as an acidulant in the food industry. It can adjust the acidity of food products and improve their taste and stability. However, its use in food is strictly regulated to ensure food safety.
Comparison with Other Related Compounds
When comparing malonic acid with other similar compounds, we can take a look at some other chemicals with different CAS numbers. For instance, Cyclohexyl Methacrylate CHMA 2 - Methyl - 2 - propenoic Acid Cyclohexyl Ester CAS 101 - 43 - 9 is an ester compound. Unlike malonic acid, which is a carboxylic acid, cyclohexyl methacrylate has a different functional group (ester group) and different chemical properties. It is mainly used in the production of polymers and coatings.
Active Diluent Butyl Glycidyl Ether BGE CAS 2426 - 08 - 6 is an epoxy compound. It has an epoxy group in its structure, which gives it different reactivity compared to malonic acid. BGE is commonly used as an active diluent in epoxy resin formulations to reduce viscosity and improve processing properties.
2 - Methylanisole/o - Cresyl Methyl Ether CAS 578 - 58 - 5 is an aromatic ether compound. It has a different chemical structure and properties compared to malonic acid. 2 - Methylanisole is used in the fragrance industry and as a solvent in some chemical processes.
