一般描述
碳酸钠（纯碱）是一种无机化合物。它用于化学品的合成、洗涤剂配方、烟气脱硫以及造纸和纸浆生产。
应用
碳酸钠可用于：
- 作为催化剂,用于合成查尔酮和扎查尔酮时醛和酮的羟醛缩合反应。
- 作为pH稳定剂，用于在柠檬香茅作为还原剂参与时合成FeO-NPs（氧化铁纳米颗粒）。
- 作为碱，用于Pd催化的铃木偶联反应。
- 作为碱，用于无过渡金属参与的铃木偶联反应，该反应使用水作溶剂且TBAB（四丁基溴化铵）作相转移催化剂催化芳基卤化物和芳基硼酸反应生成联芳基。
生化/生理作用
缓冲液成分，可用于去除外周膜蛋白。

At present, the circulating bioactivity of insulin-like growth factor I (IGF-I) is estimated by immunological measurements of IGF-I levels. However, immunoassays ignore the modifying effects of the IGF-binding proteins (IGFBPs) on the interaction between IGF-I and the IGF-I receptor (IGF-IR).

Trousseau described spontaneous, recurrent superficial migratory thrombophlebitis associated with occult cancers, and this was later correlated with disseminated microangiopathy (platelet-rich clots in small blood vessels). Trousseau syndrome often occurs with mucinous adenocarcinomas, which secrete abnormally glycosylated mucins and mucin fragments
