L-cystine HCL g?andu stabbiltà tajba
Introduzzjoni
L-cystine hydrochloride huwa ?eneralment trab kristallin abjad, li jin?all fl-ilma u s-solventi tal-alko?ol. Il-punt tat-tidwib tieg?u huwa madwar 213-216 grad Celsius. L-cystine hydrochloride g?andu stabbiltà tajba u mhuwiex fa?li biex jiddekomponi. Huwa aktar stabbli ta?t kundizzjonijiet newtrali jew kemmxejn a?idu?i, u jiddekomponi ta?t kundizzjonijiet alkalini. Barra minn hekk, il-kompost huwa sensittiv g?ad-dawl u s-s?ana u je?tie? li jin?a?en f'post frisk u niexef.
