• Description: We discuss in this Letter the association of the candidate magnetar CXOU J171405.7-381031 with the supernova remnant CTB 37B. The recent detection of the period derivative of the object allowed an estimation of a young characteristic age of only $$\sim 1000 yr$$. This value is too small to be compatible even with the minimum radius of the remnant $$\geq 10 pc$$, the value corresponding to the {\it lower} limit of the estimated distance of $$10.2 \pm 3.5 kpc$$, unless the true distance happens to be even smaller than the lower limit. We argue that a consistent scenario for the remnant origin, in which the latter is powered by the energy injected by a young magnetar, is indeed more accurate to explain the young age, and points out to its non-standard (i.e. magnetar-driven) nature.
