Description
2-Phosphonobutane-1,2,4-tricarboxylic acid (PBTC) is supplied as an aqueous solution with a minimum content of 47 % in water, CAS number 37971-36-1 and empirical formula C₇H₁₁O₉P. This organophosphonic acid is Physical data include a density of 1,27 g/cm³, a flash point above 100 °C and a boiling point of approximately 100 °C, supporting safe handling under standard aqueous conditions. PBTC is widely employed as a scale and corrosion control agent and as a complexing component in water-treatment and industrial formulation work. The ready-to-use aqueous grade simplifies dosing and dilution compared with solid phosphonates. Offered by manufacturer Carl ROTH, the product suits research groups and development laboratories that need a defined PBTC concentrate for screening, method setup and pilot trials. size is practical for repeated experiments while remaining convenient for bench storage and inventory control.

Questions about 2-Phosphonobutane-1,2,4-tricarboxylic, acid (PBTC), min. 47 % (in Water), 100 ml
What is this article?
2-Phosphonobutane-1,2,4-tricarboxylic, acid (PBTC), min. 47 % (in Water), 100 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
