This benzofuran heterocyclic intermediate is core building block for novel small-molecule pharmaceutical synthesis, widely used to construct benzofuran fused pyrimidine, quinoline and oxazole parent ring via amino condensation and ester hydrolysis reactions. It serves as key raw material for anti-inflammatory, analgesic, anti-tumor and CNS-targeted new drug APIs in pharmaceutical R&D industry. In pesticide development field, it is precursor for high-efficiency benzofuran-series fungicide and insecticide intermediates with selective biological activity against crop pathogens. Besides pharma & agrochemical, it is applied as ligand precursor for palladium catalytic cross-coupling reactions including Suzuki and Ullmann condensation in organic synthetic lab. Commercial packing: 25kg inner PE bag outer cardboard drum for bulk order; lab trial specification 1kg/5kg aluminum foil vacuum bag, regularly supplied to global fine chemical manufacturers and pharmaceutical research institutes.

GHS:H315,H319,H335；Signal Word:Warning Low-toxicity heterocyclic crystalline irritant, fine dust irritates human skin, eye conjunctiva and upper respiratory tract mucosa. Direct skin contact may cause erythema and itchiness, flush contaminated skin with abundant running clean water continuously over 15 minutes. Powder splashing into eyes leads to stinging and lacrimation, persistent eye rinsing ≥15min and seek medical advice if discomfort retains. Inhalation of suspended dust triggers dry throat and mild cough; all feeding, crushing and weighing operations must proceed inside ventilated fume hood equipped with nitrile gloves, splash-proof safety goggles and anti-dust respirator. Store separately from strong acid, oxidants and food raw materials in cool dry warehouse. Discarded residual solid belongs to general hazardous organic waste, deliver to qualified professional waste disposal institution for incineration treatment following local environmental regulation, forbidden arbitrary discharge into sewer or soil.
