title: Ethyl N-[2-(4-phen-oxy-phen-oxy)eth-yl]carbamate.
abstract: The title compound, C(17)H(19)NO(4), which is a non-toxic insect growth regulator with the common name fenoxycarb, contains two independent and conformationally different mol-ecules in the asymmetric unit. Although the inter-ring dihedral angles are similar [62.21 (15) and 63.00 (14)°], the side-chain orientations differ. In the crystal, the mol-ecules are linked through N-H⋯O hydrogen-bonding associations, giving chains which extend along [110], while intra- and inter-molecular aromatic C-H⋯π inter-actions give sheet structures parallel to [110].
