 PubChem Compound database by National Center for Biotechnology Information

Verified structural records: Cephalosporin C, CID65536; L-carnitine, CID10917; sodium tetraborate, CID10219853. Record locators and hydration/stereochemical conventions are specified where cited.

Verified EVA composition-conversion inputs: ethylene, CID 6325, pubchem.ncbi.nlm.nih.gov/compound/6325 , Molecular Formula C2H4 and Molecular Weight 28.05 g/mol; vinyl acetate, CID 7904, pubchem.ncbi.nlm.nih.gov/compound/7904 , Molecular Formula C4H6O2, connectivity CH3COOCH=CH2 and Molecular Weight 86.09 g/mol. The long-chain unit-mass conversion is derived in the ethylene-vinyl acetate article; these database records do not specify a copolymer feed-to-chain composition relation.
