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.[1]
  • To prepare pharmacologically important 2,5-DBHA-gelatin conjugate, which can act as a polymer for the development of drug formulations.[2]
  • As a tridentate ligand to synthesize complexes of molybdenum by reacting with (PPh4)4Mo8O26.[3]
  • As a starting material in the total synthesis of landomycin A, an angucycline antibiotic.[4]

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

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
