PUN91835, also known as ROX NHS ester, is a rhodamine dye linker containing NHS ester group which can be used to label the primary amines (-NH2) of proteins, oligonucleotides, and other amine-containing molecules. This product has no formal name at the moment. For the convenience of communication, a temporal code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https://www.medkoo.com/page/naming).
