Born into an aristocratic family, Białobłocki began in 1816 to study at the Warsaw Lyceum, where one of his teachers was Nicolas Chopin, the composer's father; Białobłocki lodged with the Chopin family. In 1823 Białobłocki commenced studies at Warsaw University. He became a close friend of Frédéric, who addressed numerous letters to him, using Białobłocki's nickname, Jasio.

In 1828 Białobłocki died of tuberculosis of the bone, unmarried, at his family estate of Sokołowo.
