N-七氟丁酰咪唑 HFBI 酰化试剂,在冰箱-4°C/-20°中保存即可,对水分和潮气非常敏感,在往外移取的过程中会有少量晶体析出,这是由于HFBI与空气中的水分接触发生分解反应引起的,是一种正常现象,不影响实验,建议客户每次使用完对剩余的HFBI氮吹后,拧好盖子,并用封口膜缠绕。如果客户的样品量不多,建议使用小包装的产品5X1g包装,货号为CFCQ-270611There is nothing wrong with material. However, this reagent is very sensitive to air. This is why your customer I seeing white crystals. Even the smallest exposition to air, can make the reagent react. I would recommend to your client to switch to ampoules: 5 x 1gm, Catalog #270611. It is more expensive packaging, but it lowers the chances of contamination and there is less need to re-use the same bottle of material.After packaging this material, we purge it with nitrogen, to make sure the air is removed.
