英文名称:

性质描述: 片状结晶。熔点153-154℃。溶于热水，易溶于乙醇和乙醚。
生产方法: 由3,4-亚甲基二氧基苯甲醛经下列步骤制得。将新处理过的五氯化磷分次加入3,4-亚甲基二氧基苯甲醛中，开始时反应很剧烈，需用冰水冷却，同时应防止湿气侵入。大约在加入一半五氯化磷后应变慢，可不再冷却。五氯化磷的用量为3,4-亚甲基二氧基苯甲醛的3倍（摩尔）。将所得反应液慢慢加热1h，放出氯化氢，再减压抽出挥发物。然后，将反应物倾入冷水中，析出的乳状油层放置固化。再慢慢沸腾3h，加活性炭过滤，滤液减压浓缩，冷却至0℃，析出结晶。过滤、水洗后用水重结晶，得成品。
用途: 用于有机合成。

产品说明

一般描述

3,4-Dihydroxybenzaldehyde has been recognized as one of the antifungal compound extracted from the outer skin of green Cavendish bananas. It can be synthesized from catechol via Fries rearrangement.
3,4-Dihydroxybenzaldehyde is reported as bioactive compound which inhibits the H2O2-induced apoptosis of granulosa cells. Oxidation of 3,4-dihydroxybenzaldehyde on glassy carbon electrodes is reported to afford stable redox-active electropolymerized films containing a quinone moity.

应用

3,4-Dihydroxybenzaldehyde may be used for the surface modification of nanocrystalline TiO2 particles. Electrodeposited layer of 3,4-dihydroxybenzaldehyde may be used as effective redox mediator during oxidation of NADH at graphene. It may be used in the preparation of new diSchiff base ligands, which forms di-, tri- and tetranuclear Co(II) and Cu(II) complexes.
3,4-Dihydroxybenzaldehyde (Protocatechualdehyde) may be employed as starting reagent for the synthesis of 4-vinylbenzocrown ether.
