Web25 de ago. de 2024 · Comparison of the mass balance at day 7 with and without 4-MeCHA showed an increased from 97.21% (Corrected Mass Balance) to 101.6% (Final Mass Balance) as shown in Table 6. In general at higher levels of degradation the loss of the 4-MeCHA will be more impactful and will provide a more accurate mass balance. WebMass balance calculations for accelerated stress study at 70 ˚C. Loratadine DS degradation produced increasing amounts of n-oxide, while epoxide amounts remained constant after 30 min. Correction for relative response differences of n-oxide and epoxide results in improved mass balance with 103.6% mass balance achieved
