Introduction
2-Hydroxy-4,5-dimethoxybenzoic acid (2-H4,5DMBA) is a crystalline compound with the molecular formula C₉H₁₀O₅ and a molecular weight of 198.17 g/mol. It is widely recognized as a key intermediate in the synthesis of acotiamide, a prokinetic agent used for functional dyspepsia, and serves as a building block for antioxidants, corrosion inhibitors, and specialty chemicals. Its synthesis typically involves methylation of 2,4,5-trihydroxybenzoic acid followed by hydrolysis of the corresponding methyl ester. The compound exhibits moderate thermal stability, decomposing above 213°C, and is sparingly soluble in water but soluble in organic solvents like ethanol and ethyl acetate. Due to its role in pharmaceutical pipelines and chemical synthesis, 2-H4,5DMBA is a valuable reagent in both research and industrial applications.
Usage： It is used Pharmaceutical intermediates; Intermediate of atecoline hydrochloride.
Packaging and Shipping： 25kgs/Bag or Drum or as required by buyer.
Storage: Store in a cool, ventilated place, protect from sun, heat and moisture.Storage and transportation according to general chemical regulations.
