Product Overview
Boric Acid Powder 99% ACS Grade (CAS 10043-35-3) is a high-purity, white crystalline compound known chemically as Hydrogen Borate or Orthoboric Acid. With a minimum assay of 99.0%, this ACS Reagent Grade material meets stringent specifications for impurity limits, making it suitable for analytical laboratories, precision manufacturing, and industrial formulations. It functions as a weak, monobasic Lewis acid, providing reliable pH buffering and acting as a primary boron source.
This product exhibits high solubility in boiling water and moderate solubility in cold water. It is manufactured under strict quality control to minimize trace metals (Iron, Lead) and anions (Chloride, Sulfate), ensuring consistent performance in sensitive applications such as borosilicate glass production, electroplating baths, and chemical synthesis.
