In an effort to discover novel and potential boron–dipyrromethene (BODIPY) dyes, the title compound, C 19 H 18 BF 2 N 3 O 2 , was prepared from 2,4-dimethyl­pyrrole, 4-nitro­benzaldehyde and BF 3 ·Et 2 O in a one-pot reaction. There are two independent mol­ecules,  A  and  B , in the asymmetric unit in which the dihedral angles between the benzene ring and boron–dipyrromethene mean plane have significantly different values [82.71 (8)° for mol­ecule  A  and 73.16 (8)° for mol­ecule  B ]. Inter­molecular C—H⋯π inter­actions help to stabilize the crystal structure.
