As of my last update in October 2023, there is no specific information available regarding the chemical substance with the name "INDEX NAME NOT YET ASSIGNED" and CAS number 2553412-88-5. This may indicate that the substance is either newly synthesized, not widely studied, or not yet characterized in the scientific literature. Typically, substances with unassigned index names may be in the early stages of research or development, and detailed information such as molecular structure, physical and chemical properties, safety data, and potential applications may not be readily accessible. For accurate and updated information, it is advisable to consult scientific databases, regulatory agencies, or publications that specialize in chemical substances. If this compound is of particular interest, further investigation through academic or industrial research channels may yield more insights as it becomes more recognized in the scientific community.

DBCO-PEG8-NHS Ester is a click chemistry molecule cosisting of an NHS ester  that is reactive specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. PEG8 spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions.
