Diisopropyl azodicarboxylate (DIAD) is an orange red transparent oily liquid, which is a preferred additive for producing light colored, odorless, and environmentally friendly PVC synthetic leather and flooring materials. Core technological advantages of the product 1. Low odor, high cleanliness DIAD thermal decomposition products mainly consist of nitrogen, carbon dioxide, and water, with extremely low

Pyridinium tribromide is a crystalline product widely used in fine chemicals and organic synthesis. Compared to traditional liquid bromine, it offers outstanding advantages such as high stability, safe handling, mild reaction conditions, and excellent selectivity. It serves as a superior alternative to liquid bromine and is indispensable in industries like pharmaceutical intermediates, steroid synthesis, and

The development prospects for p-toluenesulfonic acid pyridinium salt (PPTS) are robust, driven primarily by green synthesis, pharmaceutical R&D, and polymer material upgrades. However, growth is constrained by niche application scenarios and competitive alternatives, classifying it as a “key enabling reagent” rather than a bulk chemical. ‌‌ Clear Application Prospects: As a mild, anhydrous, and selective

Since 2026, the prices of upstream basic chemical raw materials have continued to fluctuate. As the core raw materials of sulfur trioxide and pyridine, the supply pattern of sulfur trioxide and pyridine is becoming increasingly tight due to the dual effects of environmental restrictions and rising energy costs. In this context, the production cost of

From June 16th to 18th, 2026, CPHI China Shanghai World Pharmaceutical Raw Materials Exhibition will be held grandly at the Shanghai New International Expo Center (Pudong). As a highly influential global professional exhibition in the pharmaceutical and chemical industry, this exhibition gathers resources from the entire industry chain of raw materials, pharmaceutical intermediates, fine chemicals,

Since 2026, with the continuous recovery of research and development investment in the domestic pharmaceutical and new materials fields, the market demand for pyridinium p-toluenesulfonate as a classic catalyst has shown a steady growth trend. At the same time, the prices of upstream raw materials such as toluene sulfonic acid and pyridine remain fluctuating within

Recently, the market volatility of fine chemical raw materials has intensified, and upstream intermediates such as hydrazine derivatives and chloroformate esters have been affected by stricter environmental policies and rising energy costs, resulting in a steady upward trend in factory quotations. As a starting point for these raw materials, the production cost of di tert

Recently, the basic chemical raw materials market has experienced frequent fluctuations, with upstream intermediates such as isobutene and trichlorophenylphosphine oxide being affected by environmental regulations and energy prices. The ex-factory quotations have shown a trend of stable yet gradual increases. As a product derived from these raw materials, dibenzoyl peroxide is now facing significant cost
