一般描述

N-甲基-N-(三甲基甲硅烷基)三氟乙酰胺(MSTFA)是一种甲硅烷基化试剂。

应用

更多信息请参见产品信息
MSTFA可用于甲硅烷基化过程,以使用GC-MS对类固醇激素17α-乙炔雌二醇(EE2)和雌酮进行测定。MSTFA与三甲基甲硅烷基氯(TMCS)一起在乙酸乙酯、乙腈和二氯甲烷溶剂中可导致三甲基甲硅烷基(TMS)和丁基二甲基甲硅烷基(TBS)衍生物的形成。
适用于胺,氨基酸,羧基,羟胺,吲哚烷基胺,正亚硝基氨基酸,核苷,酚烷基胺,5-羟色胺和色胺的衍生化。

其他说明

用于N-乙酰基-N,三氟乙酰基,三甲基甲硅烷基,N-三甲基甲硅烷基-N-三氟乙酰基和O-三甲基甲硅烷基(TMS)的试剂
高效硅烷化试剂

Glucosinolates are defense-related secondary metabolites found in Brassicaceae. When Brassicaceae come under attack, glucosinolates are hydrolyzed into different forms of glucosinolate hydrolysis products (GHPs). Among the GHPs, isothiocyanates are the most comprehensively characterized defensive compounds, whereas the functional study of

C4 photosynthesis provides an effective solution for overcoming the catalytic inefficiency of Rubisco. The pathway is characterised by a biochemical CO2 concentrating mechanism that operates across mesophyll and bundle sheath (BS) cells and relies on a gas tight BS compartment.
