Preparation

Preparation by Fries rearrangement of hydroquinone diacetate,
with aluminium chloride(91%) (76%)(63–77%) (55–60%)
with zinc chloride in refluxing acetic acid (quantitative yield)
with boron trifluoride etherate in benzene at reflux (65%).

What are the applications of Application

2',5'-Dihydroxyacetophenone inhibits the formation of reactive oxygen species and nitric oxide in rat neutrophils. It also has the ability to reduce oxidative stress by scavenging free radicals and inhibiting lipid peroxidation. The underlying mechanism for these effects is not fully understood but may be due to its ability to act as a substrate for matrix-assisted laser desorption ionization (MALDI). This means that it can react with protocatechuic acid molecules that are present in the sample preparation chamber, leading to polymerase chain reaction (PCR) amplification.

Definition

ChEBI: 2',5'-Dihydroxyacetophenone is an aromatic ketone.
