Source NH 2 CN ∕H 2 NH2CN∕NH2CHO Telescope
      
IRAS 16293 B ~0.20 ALMA
NGC 1333 IRAS2A ~ 5 × 10−11 ~0.02 PdBI
Sgr B2 (N) ~0.02–0.04 IRAM-30 m
Sgr B2 (M) ~0.15 IRAM-30 m
Orion KL ~0.4–1.5 JCMT

Low-density model ~ 3.7 × 10−10 ~ 1.1 × 10−3
High-density model ~ 6.7 × 10−12 ~ 1.3 × 10−4

Notes. (a) Based on the lower limit of 1.2 × 1025 cm−2 for the H2 abundance derived by Jørgensen et al. (2016).
