一般描述
亚硝酸钠是一种具有还原性和氧化性的空气敏感和吸湿性固体。它是合成有机化学中常用的试剂和催化剂。它被酸（甚至弱酸）分解，形成棕色的氮氧化物混合物（NOx）。
应用
亚硝酸钠可作为试剂用于：
在有机合成中也可用作硝化剂。
它用于直接碳氢硝化、同位硝化和过渡金属催化的交叉偶联硝化。在有氧、无溶剂条件下，NaNO2 也被用作醇催化氧化的助催化剂。
- 在将胺转化为重氮化合物的过程中，重氮化合物被用作许多染料的关键前体，如重氮染料。
- Nef 反应和 Abidi 转化。
- 在 TFA 和有氧条件下的 C-C 键裂解反应。
- 在 K2S2O8 环境下烯烃的氧化羰化反应。

Macrophages are classified upon activation as classical activated M1 and M2 anti-inflammatory regulatory populations. This macrophage polarization is well characterized in humans and mice, but M1/M2 profile in cattle has been far less explored. Bos primigenius taurus (taurine) and Bos

Breast tumors are inherently heterogeneous, but the evolving cellular organization through neoplastic progression is poorly understood. Here we report a rapid, large-scale single-cell resolution 3D imaging protocol based on a one-step clearing agent that allows visualization of normal tissue architecture

The literature provides evidence that metabolic nitric oxide (NO) release mediates the cytotoxic activities (against human leukemia and prostate cancer xenografts in mice) of JS-K, a compound of structure R(2)N-N(O)=NO-Ar for which R(2)N is 4-(ethoxycarbonyl)piperazin-1-yl and Ar is 2,4-dinitrophenyl.

Previous studies in non-human blood vessels and in platelets have demonstrated that under hypoxic conditions release of NO from nitrite (NO2(-)) is potentiated by deoxyhaemoglobin. In the current study, we characterized hypoxic potentiation of NO2(-) effects in human vasculature and

The new pathway nitrate-nitrite-nitric oxide (NO) has emerged as a physiological alternative to the classical enzymatic pathway for NO formation from l-arginine. Nitrate is converted to nitrite by commensal bacteria in the oral cavity and the nitrite formed is then
