Application
ß-DEX™-325色谱柱可用于气-液色谱（GLC），用于测定由2-乙基-1,3-丙二醇1形成的(R)-1-O-乙酰基-2-乙基-1,3-丙二醇及其相关的二-O-乙酸酯，通过荧光假单胞菌脂肪酶的部分化学酶促乙酰化和脱乙酰化。ß-DEX™-325毛细管色谱柱在一项实验性研究中还被用于解析8-乙酰基芳樟醇对映体，以研究猕猴桃花中丁香化合物生物合成中对映选择性的起源。
Features and Benefits
温度限制：
- 30 °C至230 °C
General description
β-DEX 325 柱中的手性固定相包含嵌入中极性相的 2,3-二-O-甲基-6-0-TBDMS-β-环糊精。Supelco β-DEX 325 与 CHIRALDEX B-DM 相的化学性质和用途都相同,主要区别在于掺入聚硅氧烷载体中的二甲基衍生的环糊精浓度不同。
Other Notes
我们提供各种色谱配件，包括 分析注射器

Biosynthesis of lilac compounds in 'Hortgem Tahi' kiwifruit (Actinidia arguta) flowers was investigated by treating inflorescences with d(5)-linalool. The incorporation of the deuterium label into 8-hydroxylinalool, 8-oxolinalool, the lilac aldehydes, alcohols, and alcohol epoxides was followed by GC-MS and enantioselective
Chiral building-blocks by chemoenzymatic desymmetrization of 2-ethyl-1, 3-propanediol for the preparation of biologically active natural products.
