Safety Information of 4-Azaindole (CAS No.272-49-1):
Hazard Codes: Xi
Hazard Note: Irritant
HazardClass: IRRITANT
4-Azaindole (CAS No.272-49-1), it also can be called 1H-Pyrrolo[3.2-b]pyridine ; 1,4-Diazaindene .It is white to off-white crystalline powder.Several 4-azaindole and 7-azaindole dimer analogues of melatonin with a bisalkoxyalkyl spacer between the position 5 of each heterocycle were synthetized. Results suggest the distance between indole ring seems to be an important parameter in determining the potency of binding with melatonin receptor site. Storage of 4-Azaindole: Keep container closed tightly, refrigerate (2-8°C), store dry, and protect from light.
