Ammonium phosphate monobasic is also referred to as monoammonium phosphate, ammonium acid phosphate, ammonium monophosphate, and ammonium dihydrogen phosphate. It is a white crystalline solid consisting of ammonium cations and dihydrogen phosphate anions in equal proportions. Ammonium phosphate monobasic is the major ingredient of agricultural fertilizers and some fire extinguishers.It also has significant uses in optics and electronics.

Our products are manufactured in various purities ranging from 99% pure up to 99.9999% pure and customer specifications for a particular application or when certain analytes are problematic for a customer’s process. In addition to supplying custom manufactured material, Noah also produces material to internationally known and accepted standards like American Chemical Society (ACS), United States Pharmacopeia (USP), National Formulary (NF), Reagent Grade, Food Chemicals Codex (FCC), Military Specifications and Standards (MIL/AMS), and American Society for Testing and Materials (ASTM).We have the capability to go from R & D laboratory quantities and scale up to full production quantities as needed. Additional technical data like Safety Data Sheets (SDS) and product specifications (as applicable) can be found on the specific product pages within this website.

Noah supplies a variety of metal compounds in common forms like acetate, boride, bromate, bromide, carbonate, chloride, chromate, fluoride, hydroxide, iodate, iodide, molybdate, nitrate, oxide, phosphate, selenite, selenide, selenite, silicate, silicide, sulfate, sulfide, titanate, tungstate, and zirconate.
