The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The t-butyl protected carboxyl group can be deprotected under acidic conditions. PEG Linkers may be useful in the development of antibody drug conjugates and drug delivery methods.Product Details:Name: Amino-PEG6-t-butyl esterCAS#: 1286281-32-0Chemical Formula: C19H39NO8Exact Mass: 409.2676Molecular Weight: 409.52Elemental Analysis: C, 55.73; H, 9.60; N, 3.42; O, 31.25Specification:Synonym: Amino-PEG6-t-butyl esterIUPAC/Chemical Name: tert-butyl 1-amino-3,6,9,12,15,18-hexaoxahenicosan-21-oateInChi Key: QGSFECNPSLZGGT-UHFFFAOYSA-NInChi Code: InChI=1S/C19H39NO8/c1-19(2,3)28-18(21)4-6-22-8-10-24-12-14-26-16-17-27-15-13-25-11-9-23-7-5-20/h4-17,20H2,1-3H3SMILES Code: O=C(OC(C)(C)C)CCOCCOCCOCCOCCOCCOCCNAppearance: Solid powderPurity: >99% (or refer to the Certificate of Analysis)Shipping Condition: Shipped under ambient temperature as non-hazardous chemical.
