5-Methoxysalicylic acid is a chemical compound belongs to the class of organic compounds known as m-methoxybenzoic acids and derivatives. It is a component of castoreum, the exudate from the castor sacs of the mature beaver.
A mixture of 5-methoxysalicylic acid and spermine can be used as a matrix for oligonucleotides analysis in MALDI mass spectrometry.
It is an isomer of vanillic acid.
2-Hydroxy-5-methoxybenzoic acid is matrix additive which enhances the electrical conductivity of the matrix crystal during matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS).
