First results of a non-singlet QCD analysis of the structure function F-2(x, Q(2)) in 3-loop order based on the non-singlet world data are presented. Correlated errors are determined and their propagation through the evolution equations is performed analytically. The value for alpha(s)(Mz) is determined to be 0.1135 +/- 0.0023/0.0026 compatible with results from other QCD analyses. Low moments for u(v)(x), d(v)(x) and u(v)(x)-d(v)(x) with correlated errors are calculated which may be compared with results from lattice simulations.
