2,4-Dimethoxy-4'-hydroxybenzophenone, also known as Rink Acid Reagent, is a linker precursor used to prepare Rink acid resin for solid-phase peptide synthesis. After reduction to the corresponding benzhydrol and attachment to a polymer support through its 4'-hydroxy group, it gives a highly acid-labile linker that releases fully protected peptide acids under very mild acidic conditions. This compound has a CAS number of 41351-30-8, a molecular formula of C15H14O4, and a molecular weight of 258.27 g/mol. It is stored at ambient conditions and carries a signal word of "Warning" for safety classification. Molekula supplies 2,4-Dimethoxy-4'-hydroxybenzophenone from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
