Basic Information and Parameters

Factory Supply 15-Crown-5, with the CAS number 33100-27-5, is a high - quality chemical product. Chemically, 15 - Crown - 5 is a crown ether with a cyclic structure of five oxygen atoms separated by ethylene groups. Its molecular formula is C10H20O5, and its molecular weight is approximately 220.26 g/mol. This product is typically supplied in a pure form, ensuring its reliability for various applications. It is a colorless liquid under normal conditions and has a relatively low melting point and a specific boiling point that makes it suitable for many chemical reactions carried out at moderate temperatures. The purity of our Factory Supply 15 - Crown - 5 is carefully controlled to meet the highest industry standards, and it comes in well - sealed containers to prevent contamination and evaporation.

Uses of the Product

15 - Crown - 5 has diverse applications in different fields. In organic synthesis, it is widely used as a phase - transfer catalyst. It can complex with metal cations, such as potassium ions, and transport them from an aqueous phase to an organic phase. This function significantly enhances the reaction rate and selectivity of many organic reactions, such as nucleophilic substitution reactions. For example, in the synthesis of certain esters or ethers, the addition of 15 - Crown - 5 can improve the yield and purity of the products.

In analytical chemistry, 15 - Crown - 5 can be used in ion - selective electrodes. Its ability to selectively bind to specific metal ions allows for the development of sensors that can accurately detect and quantify the concentration of these ions in solutions. This is crucial in environmental monitoring, where the detection of heavy metal ions in water sources is of great importance.

It also finds applications in the field of material science. For instance, it can be used in the preparation of some supramolecular materials, where its unique molecular structure can participate in self - assembly processes to form novel materials with specific properties.

How to Use the Product

When using Factory Supply 15 - Crown - 5, proper safety precautions should be taken. Wear appropriate protective equipment, such as gloves and goggles, to avoid direct contact with the skin and eyes. In a laboratory or industrial setting, it should be used in a well - ventilated area to prevent the inhalation of its vapors.

In organic synthesis, the appropriate amount of 15 - Crown - 5 should be added based on the reaction requirements. Usually, it is added in catalytic amounts, and the exact quantity depends on the nature of the reaction, the concentration of reactants, and the reaction conditions. It is recommended to add it gradually while stirring the reaction mixture to ensure uniform distribution.

In analytical applications, the preparation of solutions containing 15 - Crown - 5 should follow strict procedures. The concentration of the crown ether in the solution needs to be accurately controlled to ensure the accuracy of the detection results. After use, the remaining product should be properly stored in a cool and dry place, away from heat sources and direct sunlight.

Usage Case Studies

Case 1: Organic Synthesis
A research group was working on the synthesis of a complex organic compound. They used Factory Supply 15 - Crown - 5 as a phase - transfer catalyst in a nucleophilic substitution reaction. Before using the crown ether, the reaction had a low yield and a long reaction time. After adding an appropriate amount of 15 - Crown - 5, the reaction rate increased significantly. The yield of the target product increased from 30% to over 80% within a much shorter reaction time. This shows the effectiveness of 15 - Crown - 5 in improving the efficiency of organic synthesis reactions.

Case 2: Analytical Chemistry
In an environmental monitoring project, a team needed to detect the concentration of potassium ions in a water sample. They developed an ion - selective electrode using 15 - Crown - 5. The electrode showed high selectivity and sensitivity towards potassium ions. By comparing with traditional detection methods, the results obtained from this ion - selective electrode were more accurate and reliable, especially in samples with complex matrices. This indicates the potential of 15 - Crown - 5 in analytical applications.

User’evaluation of us

"vivalr is my partner for years. Met at 2014 Shanghai CPHI Expo. Not interested then as had stable supplier. In Sep 2016, original supplier couldn't guarantee quality and delivery. Thought of Zhai and his company first. So far, have stable business relationship and good personal friendship."

Marcus Long

" In years of sourcing from China, first found working with Sincere Chemical great. They help in production, delivery and tech, saving time. When first asking Zhai for optical brightener quote, got detailed one with prices, trade details, company info, R&D and production capacity, packaging and raw material control."

Emma Kung

" Hi, I'm Kim, Zhai's partner. Don't like him much (as he never gives more for my prices, haha), but still write customer feedback. Zhai's emails help me understand product and industry. Satisfied with his work ethic. He provides quotes and helps with work details, so I can focus on other things. He's the best supplier for me."
