Product Overview

Ammonium Bifluoride Flakes (NH4HF2) are supplied as an ACS Reagent Grade, white crystalline solid meeting the rigorous specifications set by the American Chemical Society. Also known as Ammonium Hydrogen Fluoride, this compound serves as a critical source of fluoride ions for analytical, research, and industrial applications. With a density of 1.25 g/mL at 25°C, it dissolves readily in water to create an acidic solution suitable for precision operations.

This ACS Grade material is certified for use in analytical chemistry, quality control testing, and demanding applications in electronics manufacturing, glass processing, and metal finishing. It offers a tightly controlled impurity profile that meets or exceeds ACS specifications, making it suitable for quantitative analysis, titrations, and sensitive laboratory procedures. The product is packaged to maintain dryness and flowability, ensuring consistent performance in batch processing.

  • Chemical Formula: NH₄HF₂
  • CAS Number: 1341-49-7
  • Grade: ACS Reagent Grade
  • Appearance: White crystalline flakes
  • Solubility: Highly soluble in water
  • Molecular Weight: 83.01 g/mol
  • Melting Point: -11 to -16°C (decomposes upon heating)
  • Specific Gravity: 1.25 (typical at 20°C)
  • pH Behavior: Weak acid (pKa 3.0–3.1)

Common Applications

  • Analytical Chemistry: Used as an ACS-grade reagent for quantitative analysis, titrations, and laboratory procedures requiring certified purity standards.
  • Glass & Ceramic Etching: Used extensively for etching patterns, frosting glass, and removing oxides from silicate materials.
  • Metal Surface Finishing: Acts as an efficient cleaning agent for aluminum anodizing and brightening, as well as rust removal for iron and steel.
  • Electronics Manufacturing: Serves as an etchant for silicon wafers and oxide removal in semiconductor fabrication.
  • Industrial Cleaning: Used in brewery and dairy pipe cleaning solutions to remove stone and scale buildup.
  • Chemical Synthesis: Provides a reactive source of fluoride for the production of wood preservatives and other fluorinated compounds.
  • Oil & Gas: Utilized in acidification of oil wells to dissolve silica and silicates in rock formations.

Safety & Handling

Hazmat Classification: UN 1727, Ammonium hydrogendifluoride, solid, Class 8, PG II.

Ammonium Bifluoride is corrosive and toxic. Strict safety protocols must be followed during handling:

  • PPE: Wear chemical-resistant gloves (Neoprene/Nitrile), full-face splash shield or goggles, and impervious protective clothing.
  • Storage: Store in a cool, dry, well-ventilated area in corrosion-resistant containers (HDPE or plastic). Avoid glass containers for long-term storage of solutions due to etching properties.
  • Handling: Prevent dust generation. Do not breathe dust or mist. Wash thoroughly after handling.

In the event of exposure, refer immediately to the product Safety Data Sheet (SDS) and seek medical attention. This product is for professional and industrial use only.
