Product Overview

Our Ammonium Bifluoride Flakes ACS Grade is an inorganic compound widely utilized across various industrial sectors for its highly reactive properties. As a key agent in metal treatment, glass etching, and industrial cleaning formulations, this solid chemical provides a reliable source of active fluoride. At Alliance Chemical, we ensure our ammonium hydrogendifluoride, solid, is sourced and distributed under rigorous quality management systems to maintain consistency and purity across every batch. This material is delivered in solid flake form, offering improved handling characteristics and reduced dust generation compared to fine powders during bulk manufacturing processes.

This chemical compound plays an indispensable role in critical industrial workflows, specifically where controlled chemical reactions are required. Standard applications range from oil well acidification, which helps increase permeability in geological formations, to surface preparation in metal finishing facilities. By selecting Alliance Chemical as your distributor, you secure a reliable supply chain partner capable of delivering consistent chemical quality. We understand the operational demands of manufacturing facilities and provide comprehensive documentation, ensuring our chemical solutions integrate seamlessly into your established production lines.

Why This Grade

Selecting the correct grade of ammonium hydrogendifluoride is critical for maintaining process stability and preventing manufacturing defects. While technical or industrial grades may contain elevated levels of heavy metals, iron, or sulfates, our ACS Grade material is manufactured to meet tight analytical tolerances. In precise operations like semiconductor wafer processing or specialized glass manufacturing, trace metal impurities can disrupt surface properties, leading to complete batch failure or compromised structural integrity in final products. You can explore our full range of inorganic compounds to find other suitable materials for your applications.

Using an incorrect chemical grade also accelerates equipment degradation. Higher impurity levels can cause unwanted secondary catalytic reactions or generate insoluble precipitates that clog industrial nozzles and filtration systems. By choosing this ACS Grade material, facility managers eliminate the variables associated with lower-tier products. This high-purity profile ensures reproducible reaction kinetics in chemical synthesis and predictable etching rates in surface treatment baths, protecting both your end product and your capital equipment investments.

  • Chemical Synthesis — Serving as a dependable fluorinating reagent in the synthesis of specialized organofluorine compounds and chemical intermediates.

Hazmat & Shipping

Due to its chemical properties, Ammonium Bifluoride Flakes ACS Grade is classified as a hazardous material for transport. It is officially regulated as UN1727, Hazard Class 8, Packing Group II, with the proper shipping name Ammonium hydrogendifluoride, solid. This compound carries the signal word Danger due to its corrosive and toxic nature, specifically carrying hazard statements H301 (Toxic if swallowed) and H314 (Causes severe skin burns and eye damage). Our logistics team is fully certified in handling hazardous materials, ensuring that all shipments comply strictly with DOT and international shipping regulations.

When handling this chemical, operators must strictly adhere to the precautionary statements, which include P260, P264, P270, P280, P301+P316, P301+P330+P331, P302+P361+P354, P304+P340, P305+P354+P338, P316, P321, P330, P363, P405, and P501. Appropriate personal protective equipment (PPE) is mandatory under OSHA guidelines. This includes chemical-resistant gloves, protective clothing, face shields, and eye protection. It is vital to consult the product's Safety Data Sheet (SDS) before use to understand full spill containment and emergency response protocols.

Handling & Storage

Store Ammonium Bifluoride Flakes ACS Grade in a cool, dry, well-ventilated area away from direct sunlight. To prevent container degradation, store this material strictly in original, tightly sealed polyethylene or polypropylene containers. Avoid glass, silicate, metal, or concrete storage vessels, as the chemical will react aggressively with these materials. Keep away from incompatible substances, including strong acids, strong bases, and glass-based compounds. Maintain storage temperatures within a standard ambient range, avoiding extreme heat. Proper segregation in the warehouse is essential to prevent accidental contact with reactive chemical agents.

Order & Documentation

At Alliance Chemical, we make safety and compliance our highest priority. We provide a Safety Data Sheet (SDS) with every order, and a Certificate of Analysis (COA) is available upon request for quality verification. Our team is ready to assist you with technical specifications, container options, and shipping logistics. Please Request a Quote for bulk pricing or Download the SDS for your safety records.
