Pheophorbide b ethyl ester from a chlorella vulgaris dietary supplement

In the title compound, C(37)H(38)N(4)O(6), four five-membered nitro­gen-bearing rings are nearly coplanar. Two N atoms in two these five-membered rings have attached H atoms, which contribute to the formation of intra­molecular N—H⋯N hydrogen bonds [N⋯N = 2.713 (5)–3.033 (6) Å].
