As per Regulation (EC) No. 1107/2009, repealing directive 91/414/EEC, 2,4,5-T is not approved for use in the European Union. But a default maximum residue limit (MRL) of 0.01 mg/kg is applicable for the presence of 2,4,5-T (taken as a sum of 2,4,5-T, its salts, and esters) in products of plant origin, in accordance with Regulation (EC) No. 2015/868.
Application
The 2,4,5-T CRM may also find use in the following:
- Development of a multi-residue method for the determination of 24 plant growth regulators in 50 grape samples using a modified QuEChERS method and liquid chromatography-tandem mass spectrometry (LC-MS/MS)
- Development and validation of a method that included acidified QuEChERS extraction and LC-MS/MS determinationͰ based on fast switching between positive and negative electrospray ionization modes, to analyze 35 acid herbicides in food matrices
- Application of a novel amino-modified covalent organic framework (NH2@COF) as a solid phase extraction (SPE) absorbent to extract carboxylic acid pesticides from environmental water samples
- Determination of 12 phenoxy carboxylic acids in water samples by using a metal-organic framework (MIL-101) for dispersive solid phase extraction (DSPE) followed by ultra-high performance liquid chromatographic-tandem mass spectrometric (UHPLC-MS/MS) analysis
- Analysis of 26 acid herbicides in 309 soil samples by dispersive solid-phase extraction and liquid chromatography-tandem mass spectrometry (LC-MS/MS)
- Investigating the use of magnetic polyethyleneimine-modified reduced graphene oxide (Fe3O4@PEI-RGO) as an adsorbent for the magnetic solid-phase extraction and HPLC determination of polar acidic herbicides in rice samples
