For professionals in the chemical industry, a deep understanding of a compound's fundamental chemical properties is the bedrock of successful application and innovation. 4-Methylbenzenesulfonhydrazide (TSH) is one such compound, recognized for its dual role as a potent foaming agent and a versatile organic synthesis intermediate. NINGBO INNO PHARMCHEM CO.,LTD. provides insight into the scientific characteristics that make TSH a valuable asset for manufacturers and researchers.

TSH, chemically known as p-Toluenesulfonhydrazide, possesses a molecular formula of C7H10N2O2S and a molecular weight of 186.23. Its appearance is typically a white crystalline powder. Key physical and chemical properties include a melting point in the range of 103-108°C, and a density of approximately 1.42 g/cm³. Crucially for its function as a foaming agent, TSH decomposes at elevated temperatures, releasing nitrogen gas. This controlled decomposition is influenced by factors such as heating rate and the presence of activators, allowing for fine-tuning of the foaming process in polymers and rubbers.

The reactivity of the hydrazine group (-NHNH2) in TSH makes it an excellent organic synthesis intermediate. It readily undergoes condensation reactions with carbonyl compounds (aldehydes and ketones) to form hydrazones. These hydrazones are valuable intermediates themselves, often used in further synthetic transformations such as the Wolff-Kishner reduction or as precursors for diazo compounds. The sulfonyl group (-SO2-) also influences its reactivity and stability.

The efficiency of TSH as a foaming agent for rubber and plastics is largely due to the characteristics of the gas it produces and the residue left behind. The nitrogen gas liberated creates a uniform cellular structure, providing benefits like reduced weight, improved thermal insulation, and enhanced shock absorption. The decomposition residue is generally considered non-toxic and odorless, making TSH an environmentally friendlier option compared to some other blowing agents.

For manufacturers, understanding the optimal processing conditions for TSH is vital. This includes selecting appropriate activation temperatures and ensuring good dispersion within the polymer matrix. NINGBO INNO PHARMCHEM CO.,LTD. supplies TSH that meets stringent purity standards, ensuring reliable performance in all its applications. The competitive prices offered by NINGBO INNO PHARMCHEM CO.,LTD. make this versatile chemical accessible for various industrial needs, from large-scale production runs to specialized research projects.
