Description
Amino-PEG4-propionic acid is a biochemical reagent with a minimum purity of 85 %, empirical formula C₁₁H₂₃NO₆ and CAS number 663921-15-1. The molar mass is 265,3 g/mol and the density is 1,134 g/cm³, giving laboratories clear physicochemical reference values for handling and documentation. It is supplied in a 5 g pack size suited to research-scale synthesis, method setup and inventory planning. The defined amino- and propionic-acid-bearing PEG4 structure supports work where a short polyethylene glycol spacer with dual functionality is required. Available from manufacturer Carl ROTH in the biochemicals range, the material is presented with straightforward identity data for ordering and quality records. CAS registry number, empirical formula, assay level, molar mass and density can be matched directly to internal substance lists and experimental protocols. This pack format helps teams manage consumption across multi-step projects while keeping the core analytical parameters transparent and easy to cite in laboratory documentation.

Questions about Amino-PEG4-propionic acid
What is this article?
Amino-PEG4-propionic acid 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.
Which category should I open next?
The category is Acids & bases. The sub-category is Acids. The catalogue is Lab chemicals.
