3- (cyclohexylamine) -2-hydroxy-1-propanesulfonic acid, commonly known as CAPSO buffer, is an organic compound with the chemical formula C9H19NO4S and a molecular weight of 237.31 g/mol. The CAS number is 73463-39-5. CAPSO possesses both hydrophilic sulfonate groups and highly active hydroxyl groups. This dual property enables CAPSO to exhibit strong activity and broad application potential in chemical reactions. The sulfonate group endows CAPSO with excellent water solubility, while the hydroxyl group brings it abundant reaction possibilities, such as deprotection, substitution, and other reactions.

CAPSO buffer

Characteristics of CAPSO

PH buffering range: CAPSO buffer is commonly used for neutral to alkaline pH buffering, making it very suitable for simulating pH environments under physiological conditions.

Solubility and stability: It is easily soluble in water, forms a transparent solution, and is stable under conventional experimental conditions.

Low toxicity: As a biochemical reagent, CAPSO is considered to have low cytotoxicity and is suitable for cell culture and biological sample processing.

Compatibility: CAPSO has good compatibility with many biomolecules such as proteins and nucleic acids, without interfering with their structure and function.

Application of CAPSO

Drilling fluid loss control material: Drilling fluid plays a key role in oil and gas extraction, and it needs to have multiple functions such as controlling wellbore stability, carrying rock debris, and cooling drill bits. Among them, controlling the filtration loss of drilling fluid (i.e. the amount of loss of drilling fluid through formation pores) is crucial. CAPSO, due to its molecular structure containing both hydrophobic cyclohexylamine groups and hydrophilic sulfonate groups, can regulate the rheological and filtration properties of drilling fluids.

Polymer functional monomers: In the field of polymer synthesis, CAPSO can participate in the construction of polymer chains due to its unique structure (containing both amine and sulfonic acid groups). For example, when designing smart polymers, responsive polymers, or water-soluble polymers, CAPSO can be used as a raw material to introduce specific functional groups (such as sulfonic acid groups providing ionic properties, amine groups providing reactivity or coordination ability). These characteristics make high polymers synthesized by CAPSO potentially valuable for applications in transfer systems, water treatment, nanomaterials, and other fields.

Product packaging

The reason why CAPSO can play an important role in multiple fields is due to its unique molecular structure and chemical properties. The combination of sulfonate groups and hydroxyl groups enables CAPSO to exhibit strong activity and stability in chemical reactions. This characteristic makes CAPSO an ideal organic chemical intermediate, providing abundant possibilities and choices for the preparation of chemicals.
