This report presents an efficient syntheses of two labelled internal standards [15N3]melamine and [13C3]cyanuric acid with the common substrates [15N]NH4Cl and [13C]urea, respectively. Both standards with excellent isotopic and chemical purities were prepared in good yields and could be used as internal standards without further purification.
