Chemical intermediates are the building blocks of modern industry, transforming raw materials into the sophisticated products we use daily. Among these vital compounds is 4,4'-Oxybis(benzenesulfonyl hydrazide), commonly abbreviated as OBSH. While widely recognized for its role as a foaming agent, understanding its chemical nature and applications reveals its broader significance as an industrial chemical intermediate. This article provides an overview of OBSH, its properties, and why sourcing from a reliable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. is crucial.

What is 4,4'-Oxybis(benzenesulfonyl hydrazide) (OBSH)?

OBSH is an organic compound with the molecular formula C₁₂H₁₄N₄O₅S₂. Structurally, it features two benzenesulfonyl hydrazide groups linked by an ether oxygen atom. This unique arrangement of functional groups is responsible for its characteristic properties, most notably its thermal decomposition behavior.

Key chemical and physical properties of OBSH include:

  • Appearance: Typically a white powder.
  • Molecular Weight: Approximately 358.39 g/mol.
  • Decomposition Temperature: Ranges from 158-164°C, during which it releases nitrogen gas.
  • Gas Evolution: Yields about 125-140 ml/g of gas upon decomposition.
  • Solubility: Generally insoluble in water but may show some solubility in polar organic solvents.

The Role of OBSH as a Chemical Intermediate

While its primary application is as a foaming agent, OBSH's chemical structure makes it a valuable intermediate in various synthesis routes. The presence of sulfonyl hydrazide groups (-SO₂NHNH₂) offers reactive sites that can be modified or participate in further chemical reactions. Its thermal decomposition is a specific chemical reaction that produces gaseous products, serving a purpose in material science. Therefore, it acts as a functional intermediate that facilitates the creation of expanded materials.

Applications Beyond Foaming

Although its most prominent use is in creating foams for polymers, rubber, and plastics, the properties of OBSH hint at potential for other chemical processes. The hydrazide functional groups can be involved in condensation reactions or used in the synthesis of other specialized organic compounds. However, its most established industrial role remains as a high-performance blowing agent, contributing to:

  • Rubber and Plastic Foams: For products requiring lightweight, insulation, and cushioning.
  • Wire and Cable Jacketing: Providing enhanced electrical insulation.
  • Specialty Polymer Modification: Improving the tactile or structural properties of certain plastics.
