C3 Spacer CEP is a phosphoramidite used to incorporate a three carbon spacer arm during oligonucleotide synthesis. Spacers are designed to add space either within an oligo sequence or between the oligo and a label (e.g. FAM, biotin). The C3 spacer phosphoramidite is used to incorporate a three carbon spacer arm. For the creation of longer spacer arms, multiple sequential additions can be utilized. This product is supplied in a 5 mL amber bottle with a serum vial neck style, which is compatible with most Applied Biosystems synthesizers and AKTA synthesizers of oligonucleotide synthesizers.Features:• Full chemical name—3-(4,4'-Dimethoxytrityloxy)propyl-1-[(2-cyanoethyl)-(N,N-diisopropyl)]-phosphoramidite• Molecular formula—C33H43N2O5P• Formula weight—578.7 g/mol• CAS number—NA!!• HPLC Purity—≥98.0%• 31P NMR Purity—≥98.0%; Sum of PIII impurities (141-152ppm) ≤ 0.5%For Research Use Only.
