Scheme 1

(1) Without scavenger, 100 nmol of dosimeter (d0-phenylalanine) was subjected to FPOP, generating tyrosine-like products from •OH attack on the aromatic ring. (2) Internal standard (d5-phenylalanine) added to vial. (3) BSTFA added for derivatization of both dosimeter and internal standard. (4) Products analyzed by GC/MS.
