Description
5-Carboxytetramethylrhodamine-PEG3-Azide is a PEG-linked fluorescent azide reagent offered at a minimum purity of 90 % for laboratory use. It is identified by CAS number 1380486-02-1 and the empirical formula C₃₃H₃₈N₆O₇, with a molar mass of 630,69 g/mol. delivers a practical quantity for development work, labelling experiments, and related chemical procedures that call for a carboxytetramethylrhodamine azide bearing a PEG3 spacer. This material comes from manufacturer baseclick and is described with explicit identity parameters so users can confirm suitability against method sheets and inventory records. The defined molar mass and molecular formula support accurate dosing, solution preparation, and batch documentation in research and analytical environments. Positioned among fluorescent and click-compatible azide chemicals, the product pairs specified purity with a small pack format that aids controlled consumption and reduced waste. Clear CAS, formula, and mass data simplify cross-checking with internal specifications and the associated safety documentation used for handling and laboratory compliance.

Questions about 5-Carboxytetramethylrhodamine-PEG3-Azide, min. 90 %, 5 mg, plastic
What is this article?
5-Carboxytetramethylrhodamine-PEG3-Azide, min. 90 %, 5 mg, plastic is the article on this page. Luminix Health distributes baseclick for laboratory use. It sits in Fluorescent dyes & labels, inside Dyes, stains & indicators, in Lab chemicals.
A fluorescent dye absorbs at one wavelength and emits at a longer one. As a label it is attached to a protein, a nucleic acid or a cell. Excitation and emission maxima, and the reactive group if it must conjugate, are the specification. The colour name does not tell you the wavelengths.
A dye or a stain binds, or changes colour, so that something invisible becomes visible. An indicator changes at a pH or a redox point. A fluorescent dye absorbs one wavelength and emits another, which is how a microscope or a plate reader picks it out. The excitation and emission, or the transition interval, are the specification. The colour name on the label is not. Structures are on PubChem under IUPAC names. Methods are in the PubMed literature.
