For chemists and biochemists, the selection of the right buffer is a critical decision that can significantly impact the outcome of experiments. CAPSO Buffer (CAS 73463-39-5), a zwitterionic compound, offers a valuable buffering capacity in the alkaline pH range, making it suitable for a variety of chemical and biochemical processes. Understanding its chemical properties, particularly purity, is essential when you decide to buy CAPSO Buffer. This article provides an in-depth look at CAPSO Buffer from a chemist's perspective, detailing its properties, applications, and the importance of sourcing from a reliable manufacturer and supplier.

Chemical Profile of CAPSO Buffer

CAPSO Buffer, identified by CAS number 73463-39-5, is characterized by its molecular formula C9H19NO4S and a molecular weight of 237.32 g/mol. Its chemical structure features a cyclohexylamino group, a hydroxyl group, and a sulfonic acid group, which contribute to its zwitterionic nature. This zwitterionic character allows it to act as both an acid and a base, enabling it to resist pH changes effectively. The key chemical properties relevant to chemists include:

• Useful pH Range: CAPSO Buffer is most effective in maintaining a stable pH between 8.9 and 10.3. This makes it suitable for reactions or analyses that require a moderately alkaline environment.
• pK Value: Its pKa value is approximately 9.6 at 25°C, which is central to its buffering capacity within its operational pH range.
• Solubility: CAPSO is soluble in water, typically reported as 12g/100ml or 0.1 g/mL, facilitating easy preparation of solutions.
• Purity: For chemical and biochemical applications, the purity of the buffer is paramount. Standard specifications often cite purity levels of ≥97% or ≥98%, and in some cases, higher grades (e.g., ≥99%) are available for more demanding applications. When you buy CAPSO Buffer, always check the specified purity to match your experimental needs.
• Low Metal Binding: From a chemical perspective, its minimal interaction with metal ions is a significant advantage, preventing unwanted complexation or catalytic effects.

Applications for Chemists

Chemists utilize CAPSO Buffer in several key areas:

• Biochemical Analysis: As a buffer for enzyme assays, protein purification, and other biochemical studies that operate at alkaline pH.
• Electrophoresis: CAPSO is used in buffer systems for electrophoresis, particularly for protein transfer applications like Western blotting, where its pH range is beneficial.
• Analytical Chemistry: In specific analytical procedures that require stable alkaline conditions.
