General description

Aspirin metabolite.

Application

2,5-Dihydroxybenzoic acid (2,5-DHBA) can be used:
  • As a matrix in the MALDI-TOF mass spectrometry analysis of the poly(styrene-co-pentafluorostyrene) copolymers.
  • To prepare pharmacologically important 2,5-DBHA-gelatin conjugate, which can act as a polymer for the development of drug formulations.
  • As a tridentate ligand to synthesize complexes of molybdenum by reacting with (PPh4)4Mo8O26.
  • As a starting material in the total synthesis of landomycin A, an angucycline antibiotic.

Matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) of the proteome of a tissue has been an established technique for the past decade. In the last few years, MALDI-MSI of the N-glycome has emerged as a novel MALDI-MSI technique. To assess
Polynuclear oxomolybdenum (VI) complexes of dihydroxybenzoic acids: Synthesis, spectroscopic and structure characterization of a tetranuclear catecholato-type coordinated 2, 3-dihydroxybenzoate and a novel tridentate salicylato-type coordinated 2, 5-dihydroxybenzoate trinuclear complex

The influence of the sample preparation parameters (the choice of the matrix, matrix:analyte ratio, salt:analyte ratio) was investigated and optimal conditions were established for the MALDI time-of-flight mass spectrometry analysis of the poly(styrene-co-pentafluorostyrene) copolymers. These were synthesized by atom transfer
