Description
ortho-Phosphoric acid 85 % is a high-purity mineral acid offered as ROTIPURAN® grade, minimum 85 %, p.a., ISO, for analytical laboratory use. It corresponds to CAS number 7664-38-2, empirical formula H₃PO₄ and molar mass 98,00 g/mol, with a density in the range 1,689 to 1,71 g/cm³ and a boiling point of 158 °C. The reagent is Applications include reagents and reference work where phosphoric acid of defined analytical quality is required for acids-and-bases protocols. This product from manufacturer Carl ROTH supports laboratories that need consistent p.a./ISO-grade material for method-driven workflows. Clear physical data and concentration specification facilitate safe handling planning and integration into existing procedures without extending beyond the stated analytical grade and pack format.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about ortho-Phosphoric acid 85 %, ROTIPURAN®, min. 85 %, p.a., ISO, 1 l, plastic
What is this article?
ortho-Phosphoric acid 85 %, ROTIPURAN®, min. 85 %, p.a., ISO, 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
