AMBA (2-amino-4-methylsulfonylbenzoic acid) is one of the metabolites formed from biodegradation of parent Mesotrione. Mesotrione is a selective herbicide that belongs to the triketone family, developed for use in maize culture as a substitute for atrazine. It is used for pre- and post-emergence control of common broad-leaved weeds, primarily in corn (maize). It acts by inhibiting the p-hydroxyphenylpyruvate dioxygenase (HPPD) enzyme, thus, blocking the production of carotenoid pigments in susceptible plants.
Mesotrion is currently approved for its use in the European Union. Maximum residue levels (MRLs) have been set according to Reg (EU) 2017/626 for mesotrione for various products of plant and animal origin from 0.01 to 0.05 mg/kg. Compared to the parent compound, AMBA metabolite is more persistent in soil and possess greater toxicity in selected microorganisms.

應用
The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques. The CRM may also find following uses:
- Study the biodegradation and toxicity of herbicide mixtures mesotrione, nicosulfuron, and S-metolachlor by a bacterial strain, Bacillus sp. Mes11
- Isolation and characterization of a Bacillus sp. from cloud water for rapid biotransformation of mesotrione herbicide
- Investigation of mesotrione biodegradation products by the bacterial strain Bacillus sp. 3B6 using liquid chromatography/electrospray ionization quadrupole time-of-flight mass spectrometry (LC/ESI-QTOF-MS)
- Qualitative and quantitative metabolic profiling of mesotrione, by the bacterial strain Bacillus sp. 3B6 using NMR, LC-NMR, and LC-MS
- Method development for the determination of the mesotrione and its two metabolites, MNBA and AMBA in rice, rice plants, rice hulls, water, and soil using UPLC and triple-quadrupole tandem mass spectrometry
