Similarly belonging to strong bases, Potassium tert-Butoxide, compared to common strong bases such as sodium ethoxide and sodium hydroxide, preferentially triggers elimination reactions and is difficult to undergo substitution reactions. The core reason is its extremely high steric hindrance, as well as its special properties of strong alkalinity and weak nucleophilicity. These two factors together completely change the reaction selectivity.

1、 Pharmaceutical industry (largest application area) Synthetic raw materials and pharmaceutical intermediates: used for the preparation of anticancer drugs, cardiovascular drugs, antiviral drugs, and cephalosporin antibiotics; Complete the generation of enol salts, intramolecular cyclization, dehydrohalogenation, Buchwald Hartwig amination (C-N bond construction), reduce by-products, and improve the purity of the finished product.

Trimethyl Orthoacetate is a highly active intermediate in the fine chemical industry, which combines four reaction characteristics: condensation, methylation, carbonyl protection, and dehydration closure. Its core covers five major fields: pharmaceuticals, pesticides, fragrances, new materials for coatings, and organic synthesis laboratories.

Potassium tert-Butoxide belongs to the category of steric hindrance strong bases, with strong alkalinity and weak nucleophilicity, and is not prone to side reactions. It is a core base reagent for the synthesis of pharmaceutical intermediates and is commonly used for deprotonation, condensation, cyclization, etc Wittig、 Coupling and elimination reactions are widely used in the custom synthesis of active pharmaceutical ingredients, chiral drugs, heterocyclic intermediates, and CDMO.

Phosphoric acid is a core intermediate in the phosphorus chemical industry, divided into four categories: wet process industrial phosphoric acid, thermal refined phosphoric acid, food grade, and electronic high-purity grade. It relies on three core characteristics: acidity, chelation, and phosphorus source supply, and runs through nine major sectors: basic chemical, fine chemical, new energy, electronics, metallurgy, daily chemical, water treatment, pharmaceuticals, and agrochemicals. The following is a breakdown of the chemical industry track:

Nitroguanidine belongs to Class 1.1 explosives, which are prone to explosion due to impact, friction, and high temperature in a dry state. The dust is toxic and irritating to the respiratory tract. Strict control requirements apply to operation, storage, transportation, emergency response, and protection, and are explained in six modules:
