Description
Phosphoric acid, mono(4-nitrophenyl) ester is an aromatic phosphate monoester used as a biochemical and analytical reagent. It is identified by CAS number 330-13-2, empirical formula C₆H₆NO₆P, and a molar mass of 219,09 g/mol. The 4-nitrophenyl phosphate structure is widely recognised in enzyme assays, particularly for phosphatase activity, where release of 4-nitrophenolate provides a convenient spectrophotometric readout. Physical characteristics include a flash point of 230,7 °C and a boiling point of 457,8 °C. This material is Supplied by manufacturer Carl ROTH, it fits workflows that require a defined nitrophenyl phosphate ester for kinetic studies, method validation, or teaching laboratories. Documented identity data—CAS, formula, and molar mass—simplify purchasing specifications and laboratory records. quantity provides a practical balance between continuous assay demand and efficient stock management for groups working routinely with phosphate ester substrates.

Questions about Phosphoric acid, mono(4-nitrophenyl) est, er, 50 g
What is this article?
Phosphoric acid, mono(4-nitrophenyl) est, er, 50 g 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.
