The molecule is a pyrimidine 2'-deoxyribonucleoside that is 5-hydroxymethyl-2'-deoxyuridine in which the hydroxymethyl group at position 5 has been formally converted to the corresponding 2-aminoethyl ether. It is a thymidine hypermodification replacing 40% of thymidine nucleotides in the Salmonellaphage ViI. It is a pyrimidine 2'-deoxyribonucleoside and a primary amino compound. It derives from a 5-hydroxymethyl-2'-deoxyuridine.
