Pimelic acid, with the CAS number 111 - 16 - 0, is a dicarboxylic acid. Its chemical formula is C₇H₁₂O₄. It is a white crystalline powder under normal conditions. The melting point of pimelic acid is around 105 - 107 °C, and it has a boiling point of approximately 272.5 °C at 760 mmHg. The density of pimelic acid is about 1.17 g/cm³. It is soluble in ethanol, ether, and hot water but sparingly soluble in cold water.
Our factory - supplied pimelic acid is of high purity, which can meet various industrial and scientific research needs. The high - quality control process ensures that the impurities in the product are extremely low, providing a reliable raw material for downstream applications.
Pimelic acid has a wide range of applications in different fields. In the field of organic synthesis, it is an important intermediate for the synthesis of various organic compounds. For example, it can be used to synthesize polyesters, which are widely used in the production of plastics, fibers, and coatings. The polyesters synthesized from pimelic acid have good mechanical properties and chemical stability.
In the pharmaceutical industry, pimelic acid and its derivatives have potential biological activities. Some studies have shown that they may be used in the development of drugs for treating certain diseases. It can also be used in the production of flavors and fragrances. The esters of pimelic acid can impart unique scents to products, making them suitable for use in the perfume and cosmetic industries.
When using pimelic acid, appropriate safety precautions should be taken. Wear appropriate protective clothing, gloves, and eye protection. Avoid inhalation, ingestion, and contact with skin. When handling pimelic acid, it is recommended to use a fume hood to prevent the spread of dust.
In organic synthesis reactions, pimelic acid is usually added as a reactant to the reaction system under appropriate reaction conditions, such as temperature, pressure, and solvent. The reaction conditions need to be carefully controlled according to the specific reaction requirements. For example, when synthesizing polyesters, pimelic acid reacts with diols under the action of catalysts. The reaction temperature is generally in the range of 150 - 250 °C.
In the pharmaceutical and flavor industries, the dosage of pimelic acid needs to be accurately calculated according to the formulation and production requirements. It is usually dissolved in appropriate solvents before use to ensure uniform mixing and dispersion.
Case 1: Polyester Production
A plastics manufacturing company used our pimelic acid to produce high - performance polyesters. They mixed pimelic acid with 1,4 - butanediol in a molar ratio of 1:1 in a reaction kettle. A small amount of titanium - based catalyst was added, and the mixture was heated to 200 °C under nitrogen protection. After a few hours of reaction, a polyester with excellent mechanical properties was obtained. This polyester was used to manufacture plastic products such as beverage bottles and electronic device casings, which showed good transparency and impact resistance.
Case 2: Pharmaceutical Research
A pharmaceutical research institution used pimelic acid as a starting material to synthesize a new drug candidate. They modified the molecular structure of pimelic acid through a series of chemical reactions. In vitro experiments showed that this new compound had significant inhibitory effects on certain cancer cells. Further research is being carried out to evaluate its potential as an anti - cancer drug.
Case 3: Flavor and Fragrance Industry
A perfume company used pimelic acid to synthesize a new ester for perfume production. They reacted pimelic acid with a specific alcohol in the presence of an acid catalyst. The resulting ester had a pleasant floral fragrance. It was added to a perfume formula, and the perfume received positive feedback from consumers due to its unique and long - lasting scent.
