Dear Customer:

The current international situation is complex and volatile, and uncertain tariff policies may potentially impact our product prices. Given these uncertainties, we value your understanding regarding order-related matters.

If you decide to place an order during this period, we reserve the right to adjust the price based on the evolving situation. We understand that market changes may cause inconvenience. We will negotiate with you if there’s a significant price fluctuation due to tariff policy changes before the order’s actual delivery, and in such cases we may adjust or cancel the order as necessary.

一般描述

我们致力于为您提供更环保的替代产品，以符合“绿色化学的12项原则”的一项或多项原则要求。作为一种环保型溶剂，庚烷是色谱纯化中更加绿色的己烷替代品，因此已被升级为“更安全的溶剂和辅助剂”。点击此处了解更多详情。
溶剂选择的工具和技术：环保溶剂选择指南。

庚烷（正庚烷）是一种直链烃。据报道，其十六烷值为56。[1]

应用

HPLC级己烷的环保替代产品。
庚烷（正庚烷）可组成溶剂混合物，用于通过TLC（薄层色谱法）纯化脂肪酸甲酯（FAME）的 N-酰基吡咯烷衍生物。[2]

特点和优势

    Hierarchically structured, superoleophobic surfaces are demonstrated that display one of the lowest contact angle hysteresis values ever reported - even with extremely low-surface-tension liquids such as n-heptane. Consequently, these surfaces allow, for the first time, even ≈2 μL n-heptane droplets
