Mono-BOC-cystamine (mono BOC protected cystamine) is a tert-butyloxycarbonyl (BOC) derivative of cystamine used as crosslinker in biotechnology and molecular biology applications.^[1] This compound was originally reported by Hansen et al.^[2]

Uses[edit]

The disulfide chain allows the mono-BOC-cystamine to be easily cleaved, allowing removal of the tagging residue when desired.

Mono-BOC-cystamine is used as a crosslinker for the synthesis of cleavable photo-cross-linking reagent.^[3]

Mono-BOC-cystamine is used as a crosslinker for the synthesis of a biodegradable cystamine spacer in PGA-cystamine-Gd-DO3A, which shows improved MRI contrast for breast carcinoma imaging in mice. ^[4]
