redirect

• Why does glucosazone redirect here. It needs it's own page. SemperBlotto (talk) 14:20, 14 October 2017 (UTC)

because glucose + this = glucosazone. it is a form of osazone; have redirected there and will add a bit about it there. Jytdog (talk) 15:37, 15 October 2017 (UTC)

Preparation

There's a mistake here in the preparation of phenylhydrazine. If you react the diazonium salt with sodium sulfite you get a sulfonyl derivative and not the intended phenylhydrazine as you can seen in diazonium salt.Claudio Pistilli (talk) 12:31, 28 December 2018 (UTC)

It's cited. Check the cite and tell us what it says. But I also just checked SciFinder: of 103 specific reaction matches for aniline->phenylhydrazine, 24 note use of Na₂SO₃ or NaHSO₃ as the reducing agent (only 2 note use of Na₂S₂O₅). DMacks (talk) 13:47, 20 June 2019 (UTC)
