N-Methyliminodiacetic acid is an organic compound with the formula CH₃N(CH₂CO₂H)₂. It is a white solid, which as its conjugate base CH₃N(CH₂CO−2)₂ is used as a chelating agent for iron.^[2] It is a component of organoboron reagents as well.^[3]

Synthesis and reaction

It is prepared from imidodiacetic acid by N-methylation using the Eschweiler–Clarke reaction:^[4]

MIDA boronates are derivatives with the formula CH₃N(CH₂CO₂)₂BR, where R is a cross-coupling partner.^[5]
