The conservation of chemoselectivity becomes invalid for multiple electrophilic warheads during protein bioconjugation. Consequently, it leads to unpredictable heterogeneous labeling of proteins. Here, we report that a linchpin can create a unique chemical space to render site-selectivity for histidine and aspartic acid modification overcoming the pre-requisite of chemoselectivity.
