HD 210424 is a suspected Chemically Peculiar star in The general catalogue of Ap and Am stars by Renson et al. (1991A&AS...89..429R). To investigate if HD 210424 is really a CP star, we obtained time-resolved high-resolution spectra of this star in the 482-513nm region. The H_β line can be matched by an ATLAS9 (Kurucz 1993IAUCo.138...87K) model with solar abundances, T_eff=13200K and logg=4.0. The overall flux distribution between 150 and 600nm can be reproduced by a unique ATLAS9 model with T_eff=13450K and logg=4.0. Abundances, obtained using WIDTH9 (Kurucz, priv. comm.), are typical of a normal B-type star. Spectral line variations, characterizing CP stars, are absent on a seven day time scale.
