Applicant's summary and conclusion

Conclusions:
The test substance has a boiling point > 280°C under 101.3ka (measured by Siwoloboff). The boiling point of test substance was extrapolated to be 410°C at 101.3ka.
The test substance (source substance) bis(hydrogenated tallow C16-C18-alkyl)hydroxylamine is a structurally very similar substance to target substance hydroxylamines, di-C16-18 (even numbered) alkyl. It can be reasonably assumed that target substance has the similar boiling point range.
