元素~(35)S和~(35)S-硫脲是合成许多~(35)S标记化合物的原料。如制备生物工程研究用的~(35)S-蛋氨酸和各种~(35)S标记核苷酸。元素~(35)S的制备:将37GBq(1.0Ci)Na_2~(35)SO_4水溶液置入反应瓶中,再加入浓H_3PO_4和SnCl_2·2H_2O还原剂(70m l浓
Elemental ~ (35) S and ~ (35) S-thiourea are the starting materials for the synthesis of many ~ (35) S labeled compounds. For example, ~ (35) S-methionine and various ~ (35) S-labeled nucleotides were prepared for bioengineering. Preparation of elemental (35) S: 37GBq (1.0Ci) Na_2 ~ (35) SO_4 aqueous solution was placed in the reaction flask, and then concentrated H_3PO_4 and SnCl_2 · 2H_2O reductant
