Techniques to directly laser cool and trap molecules at ultracold temperatures have revealed a new path towards the full quantum control of a diverse range of species with a variety of internal structures. Our experiment will capitalize on this generality by directly laser cooling and trapping CH radicals for tests of ultracold organic chemistry. The low mass and blue optical transitions in this species lead to high recoil velocities which can significantly reduce the photon budget and rovibrational closure needed to slow, cool and trap a molecular beam from our cryogenic source. Here we will present the latest results characterizing our slow molecular beam and probing the chemistry of CH radicals at ~1 K.
