Chlorpyrifos
This standard substance is mainly used for residual detection of corresponding pesticide components in the fields of food, agriculture, environment, etc. The relevant production departments and testing departments are responsible for Laboratory quality control, calibration of analytical instruments, confirmation and evaluation of analytical methods, etc
Description
This standard substance (Chlorpyrifos, molecular formula: C9H11Cl3NO3PS, CAS number: 2921-88-2) is purified using commercially available raw materials obtained through purification processes such as recrystallization, the main components are determined through qualitative analysis, and after initial purity and uniformity tests meet the requirements,dry and pack.

Application
This standard substance uses two different principles and confirmed purity measurement methods to reliably trace the quantity to the SI basic unit of the substance, such as moles (mol). For the quality balance method, appropriate calibration procedures and measurement standards (including standard substances) are adopted to ensure traceability based on the contribution of impurity content and measurement uncertainty to the purity calibration results and uncertainty at the quantitative level of purity;
For differential scanning calorimetry, temperature and heat flux corrections are performed using thermal analysis standard substances (indium) (GBW (E) 130182) and (lead) (GBW (E) 130184), and the traceability of measurement results is ensured through the use of verified/calibrated weighing equipment.
