For professionals in the pharmaceutical, food, and chemical industries, understanding the precise specifications of raw materials is critical for successful product development and manufacturing. 2-Hydroxypropyl-beta-cyclodextrin (HPBCD) is a versatile compound whose performance is directly tied to its quality and characteristics. As a leading manufacturer and supplier of HPBCD, we are committed to providing clarity on its specifications, ensuring our clients can make informed purchasing decisions. This guide will help you navigate the essential details when you consider buying HPBCD.

The most fundamental identifier for HPBCD is its CAS number: 128446-35-5. This unique identifier is crucial for regulatory compliance, product tracking, and accurate sourcing. When procuring HPBCD, always verify that the CAS number matches your requirements. Beyond the CAS number, purity is a paramount specification. Our HPBCD is typically offered at high purity levels, often exceeding 98% or even 99%, depending on the grade. High purity ensures minimal interference from impurities, leading to more predictable and reproducible results in your applications, whether for pharmaceutical formulation or chemical synthesis.

Physical properties are also key indicators of quality. HPBCD typically appears as a white solid or powder. Its molecular weight is a complex value due to the variable degree of hydroxypropyl substitution, but theoretical analyses often cite a figure around 1541.54 g/mol for a common substitution pattern. Its solubility is another critical parameter; HPBCD is generally soluble in water and DMSO, which are common solvents in laboratory and industrial settings. Understanding these physical characteristics helps in handling, storage, and formulation planning.

When discussing applications, HPBCD is frequently lauded for its role as a solubilizer and stabilizer. Its ability to form inclusion complexes with hydrophobic molecules is central to its function. This complexation can significantly increase the aqueous solubility and improve the stability of APIs, food colorants, and other active compounds. For instance, in pharmaceuticals, HPBCD can enhance the bioavailability of poorly soluble drugs. In the food industry, it can improve the color intensity and light stability of natural colorants. Our team can provide detailed technical data sheets and application notes to support your specific use case when you buy from us.
