| titleOfInvention |
Phenol derivative and its use in colorimetric analysis of metal ions |
| abstract |
A phenol derivative obtained by reacting a carboxylic acid anhydride with a phenol compound, followed by condensation with iminodiacetic acid and formaldehyde, or a salt thereof is effective as an agent for adjusting color forming resistivity in a colorimetric analysis of metal ions in a fluid such as a living body fluid. |
