Corby (2016) reported the detection of several complex organic molecules in absorption at various velocities toward Sgr B2 based on the PRIMOS survey1. In particular, she detected HC3N, CH3CHO, and NH2CHO in the Scutum arm at a systemic velocity of about 25 km s−1, but CH3OH was not detected in absorption at this velocity due to contamination with maser emission. Therefore, the detections of CH3OH and CH3CN in the Scutum arm reported in Thiel et al. (2017) remain new, and they confirm the presence of complex organic molecules in spiral arm clouds outside the galactic center first reported by Corby (2016). We became aware of the PRIMOS results of Corby (2016) on complex organic molecules only after the publication of Thiel et al. (2017). The results and conclusions of our Letter are not affected.
