3-叠氮基-D-丙氨酸盐酸盐是一种叠氮基修饰的盐酸 D-丙氨酸 (D-alanine)，可用于点击化学标记。它含有 Azide 基团，可以和含有 Alkyne 基团的分子发生铜催化的叠氮-炔环加成反应（CuAAc)。它还可以和含有 DBCO 或 BCN 基团的分子发生环张力促进的炔-叠氮环加成反应 (SPAAC)。 3-Azido-D-alanine hydrochloride is an azido-modified D-alanine hydrochloride. It can be used in the research of click chemistry labeling[1]. It contains an azide group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing alkyne groups. It can also undergo ring strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing DBCO or BCN groups.
