Aminoguanidine Bicarbonate(cas2582-30-1) has something which you don't know

First,process for drying aminoguanidine bicarbonate(cas2582-30-1) 

A process for drying a wet cake of aminoguanidine bicarbonate(cas2582-30-1) (AGB), which comprises subjecting the wet cake of aminoguanidine bicarbonate(cas2582-30-1) to drying temperatures from about 35 carbon dioxide-containing atmosphere for a sufficient amount of time to form a dried aminoguanidine bicarbonate(cas2582-30-1) product which is substantially free of moisture.

Second,determination of aminoguanidine bicarbonate(cas2582-30-1) by UV spectrophotometry

A UV method for determination of aminoguanidine bicarbonate(cas2582-30-1) was established. In acid medium, paradimethylaminobenzaldehyde could reversibly react with hydrazine sulfate, and their orange product had maximum absorption at 460nm. However,  paradimethylaminobenzaldehyde could also react with aminoguanidine bicarbonate(cas2582-30-1) simultaneously in the same reaction system, the product was more stable, and that made the orange compound decomposed and faded. The reaction accorded with Beer's Law when the concentration of 1 was less than lmmol/L.

Third,carbonate and semicarbazide tin(IV) derivatives of aminoguanidine bicarbonate(cas2582-30-1).

Equimolar reactions between organotin(IV) precursors of SnClxR4-x (R = Bu, Ph, x = 1, 4) and aminoguanidine bicarbonate(cas2582-30-1) in methanol has afforded 2:1 and 1:1 (M:L) carbonate complexes as well as 1:2 semicarbazide derivative. The products were characterised by spectroscopic methods such as multinuclear NMR (H-1, C-13 and Sn-119), Myssbauer and infrared spectroscopy as well as microanalysis and melting point. The butyl and phenyl derivatives have a 4- and 5-coordinated metal centre respectively with bridging-bidentate and bridging-tridentate carbonate. For the tetrahalide metal precursor, a 6-coordinated tin(IV) derivative has been achieved with a bidentate semicarbazide towards the metal centre.
