CMP-9-azido-Neu5Ac (CMP-C9-azido-sialic acid)

CMP-9-azido-Neu5Ac is a CMP-activated sialic acid analogue bearing an azide at C9. It provides a potential bioorthogonal conjugation handle in an enzymatic labeling workflow. The position of the azide distinguishes it from CMP-Neu5Az, which contains an N-azidoacetyl group. Product selection Request the full structure, counterion and lot documentation before selecting an identity number or preparing molar solutions. CMP is a monophosphate nucleotide. Product selection and documentation Reference identifiers describe the labelled chemical form; they do not establish the counterion or hydration of a particular lot. Confirm the supplied form, assay, purity method and storage conditions on the lot certificate of analysis. Use the lot-specific formula weight when preparing molar solutions. Experimental planning Enzyme acceptance depends on the transferase, acceptor and reaction conditions. Validate the donor with your enzyme system; nucleotide sugars should not be assumed to enter cells simply because related monosaccharide precursors do.
