Description
ortho-Phosphoric acid 85 % is a VLSI Grade inorganic acid with empirical formula H₃PO₄, CAS number 7664-38-2 and molar mass 98,00 g/mol. The material shows a density in the range 1,689 to 1,71 g/cm³, a boiling point of 158 °C and EG number 231-633-2. It is supplied in a 2,5 l plastic pack suitable for laboratory and process handling. This high-concentration phosphoric acid from manufacturer Carl ROTH is specified as VLSI Grade for applications that demand tightly controlled purity. Its defined physical properties support reproducible use in etching, cleaning, sample digestion and other wet-chemical procedures where 85 % ortho-phosphoric acid is required. The plastic container format aids safe storage and transfer in regulated chemical environments. With clear identity data and VLSI quality, the product offers a consistent reagent option for facilities that standardise on high-purity mineral acids for analytical and manufacturing workflows.

Questions about ortho-Phosphoric acid 85 %, VLSI Grade, 2.5 l, plastic
What is this article?
ortho-Phosphoric acid 85 %, VLSI Grade, 2.5 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Acids, inside Acids & bases, in Lab chemicals.
An acid on this shelf is the substance itself, concentrated or as a stated solution: hydrochloric, sulfuric, nitric, acetic and the rest. Concentration, purity and the trace metals decide the use. A concentrated acid and a volumetric solution of the same name are different products, and both burn.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
