Butylstannoic Acid is an organotin compound mainly used as a catalyst in esterification, polycondensation and transesterification reactions. It is also known as Monobutyltin Oxide and MBTO. The product helps manufacturers improve reaction speed and obtain better process control in selected resin, ester and polymer production systems.

ChemicalBull supports B2B buyers with COA, MSDS, TDS, purity information, packing details and commercial quotations. Buyers can share their required quantity, application, grade and delivery location to receive suitable supply information.

Overview of Butylstannoic Acid

Butylstannoic Acid is an organotin catalyst with the commonly used CAS Number 2273-43-0. Its molecular formula is generally represented as C₄H₁₀O₂Sn. It is supplied as an amorphous white or off-white solid powder.

The product is commercially known by several names, including Monobutyltin Oxide, Monobutyltin Hydroxide Oxide, Butylstannonic Acid and Butylenestannonic Acid. These names may refer to the same commercial organotin material.

Butylstannoic Acid is especially useful in reactions involving organic acids and alcohols. It can support ester formation while helping to reduce some unwanted side reactions under suitable processing conditions.

The exact tin content, purity, moisture, particle size and catalytic activity can vary between grades. Buyers should confirm all important parameters from the batch-specific Certificate of Analysis and Technical Data Sheet.

Applications of Butylstannoic Acid

Polyester Resin Production

Butylstannoic Acid is used as a catalyst in the manufacture of polyester resins. It helps support the reaction between polyhydric alcohols and organic acids during polyester production.

Plasticizer Manufacturing

The product may be used as an esterification catalyst in the production of selected ester plasticizers. It helps speed up the reaction between alcohols and carboxylic acids.

After the reaction, the finished plasticizer should be checked for colour, acidity, purity, moisture and performance in the intended polymer system.

Alkyd Resin Formulations

Butylstannoic Acid can be used in selected alkyd resin manufacturing processes. Alkyd production involves esterification and polycondensation reactions, where an organotin catalyst may improve reaction efficiency.

Specialty Ester Production

The product is used in the manufacture of different specialty esters for industrial applications. It can support reactions involving fatty acids, glycols and other suitable alcohols.

Transesterification Reactions

Butylstannoic Acid may be used as a catalyst in selected transesterification processes. These reactions involve the exchange of an ester group with another alcohol.

The catalyst level and processing conditions should be selected according to the raw materials and required final product.

Silicone Curing Systems

Butylstannoic Acid may be evaluated as a catalyst in selected silicone and siloxane systems. Its suitability depends on the silicone chemistry, moisture level and required curing speed.

Compatibility and shelf-life testing should be completed before commercial production.

Why Choose ChemicalBull for Butylstannoic Acid?

ChemicalBull follows a specification-based sourcing process. Our team checks the required purity, tin content, application and order size before confirming product availability.

This is important because organotin catalyst grades may differ in moisture, physical form and catalytic performance. ChemicalBull helps buyers review available technical documents before placing a bulk order.

We also support regular procurement planning, packing coordination and delivery communication for industrial production requirements.

Quality, Compliance and Safety 

Butylstannoic Acid is an organotin industrial chemical and should be handled only by trained workers. Buyers must review the current MSDS and ensure that workplace exposure, storage and waste-disposal controls meet applicable requirements.

The supplied product should be checked against the agreed COA before use. ChemicalBull does not recommend food, pharmaceutical, agricultural or direct consumer applications unless the exact grade is legally approved for that purpose.
