Import Ammonium Hydrogen Difluoride Cas: 1341-49-7 — Buy in Bulk from Supplier in China

Ammonium hydrogen difluoride CAS 1341-49-7 from Hebei Tianao Technology Co., Ltd is a white crystalline inorganic compound with the molecular formula NH4HF2 and a molecular weight of 57.04 g/mol. This industrial-grade chemical is supplied as a fine powder or granular solid, typically used in applications requiring precise etching and cleaning capabilities. The compound’s high solubility in water (approximately 63 g/100 mL at 20°C) and strong acidic properties make it suitable for chemical reactions in controlled environments.

The product is primarily deployed in semiconductor manufacturing for silicon wafer etching, where its ability to remove metal oxides without damaging the substrate is critical. It is also a key intermediate in the production of aluminum fluoride and other fluoride salts, as well as in glass etching and metal surface treatment processes. Standard industrial grades for this compound often specify a minimum assay of 98.0%, with impurities such as free HF, sulfates, and heavy metals tightly controlled to meet downstream processing requirements.

Industrial buyers in electronics, metallurgy, and chemical synthesis sectors source this compound for its reliability in high-precision applications. The material is typically packaged in 25 kg or 50 kg polyethylene-lined drums to prevent moisture absorption and contamination during transit. Buyers should confirm compliance with local hazardous materials regulations, as ammonium hydrogen difluoride is classified as corrosive and requires appropriate handling and storage protocols.
