RESOMER^® RG 504 is a lactide-based copolymer containing a purified poly(D,L-lactide-co-glycolide) (CAS no. 26780-50-7) for a minimal residual monomer content and advanced performance. RESOMER^® RG 504 is specially recommended for pharmaceutical applications where controlled drug release is essential, including long-acting medication delivery systems, in-situ depot formulations, drug-loaded implants, and more, offering compatibility with a range of pharmaceutical substances, small molecules, proteins, and peptides. RESOMER^® RG 504 is recommended for processing by injection molding and provides a degradation period of 3 months max.

RESOMER^® RG 504 complies with FDA, GMP, EHS, DIN ISO 9001, MAF, and DMF regulations.

RESOMER^® polymers have been purified for a reduced residual monomer content and are available in a variety of molecular weights and viscosity ranges to meet application needs. All polymer properties can also be adjusted to match formulation requirements.
