Introduction
GB/T 35672—2017 Standard Overview
This standard is the technical specification for the original drug of clofopyralid 2-ethylhexyl ester, covering comprehensive regulations from quality requirements to test methods.
Comparison table of standard frameworks
| Dimensions | GB/T 35672—2017 | Comparison of relevant standards |
|---|---|---|
| Technical indicators | Mass fraction of clofopyralid 2-ethylhexyl ester/% ≥97.0 | Higher than the standards of some pesticide technical materials |
| Detection method | High performance liquid chromatography and gas chromatography | Consistent with other pesticide standards |
| Storage and transportation safety | Strict packaging requirements, low toxicity classification | Comply with international pesticide management regulations |
Interpretation of core clauses
Applicable scenarios of high performance liquid chromatography
High performance liquid chromatography mentioned in the standard is a commonly used method for detecting pesticide components. For example, when determining the mass fraction of clofopyralid 2-ethylhexyl ester, methanol and water are used as mobile phases, and a UV detector is used for separation and quantitative analysis. This method has the characteristics of high sensitivity and good repeatability.
The importance of acetone insoluble matter determination
The index of acetone insoluble matter (≤0.2%) reflects the purity of the product. In practical applications, if the insoluble matter exceeds the standard, it may indicate that there are problems with the production process or raw materials.
Implementation recommendations section
- Production link:Strictly control the quality of raw materials in accordance with standard requirements, optimize the synthesis process, and reduce the generation of impurities.
- Testing process:The laboratory should be equipped with advanced chromatographic instruments and calibrate the equipment regularly to ensure data accuracy.
- Packaging and transportation:Select packaging materials that comply with GB 3796 to ensure that the product is not exposed to moisture and sunlight during storage and transportation.
- Safety measures:Operators must wear protective equipment and strictly abide by the safety tips and emergency treatment suggestions in the standard.
