N-Butylphthalimide (CAS 1515-72-6) is a classic phthalimide fine chemical intermediate, widely used in pharmaceutical raw material synthesis, agrochemical pesticide intermediates, organic synthesis and fine chemical industries. Our product adopts high-purity phthalic anhydride and n-butylamine as raw materials via high-yield cyclization synthesis technology, low impurity, stable crystal form, low heavy metal content, fully compliant with TSCA, REACH pre-registration requirements for global export. This compound has stable chemical structure under normal temperature, excellent solubility in most organic solvents, convenient post-treatment and purification in synthetic routes. It is a key building block for preparing amine derivatives, pharmaceutical APIs, herbicide intermediates and specialty fine chemicals. Compared with low-purity industrial substitutes, our high-purity grade reduces side reactions during synthesis, improves target product yield and color stability.
