*Note: When combining a large number of compounds with different chemical functionalities, mix stability can be an issue. In formulating these standards, we extensively studied the 204 compounds involved, and then grouped them into as few mixes as possible while still ensuring maximum long-term stability and reliability. For quantitative analysis, we recommend analyzing each mix separately to ensure accurate results for every compound.

^†Reference materials containing chlorantraniliprole (500008-45-7) must be sonicated for a minimum of 60 minutes prior to opening the ampul. Because each ultrasonic bath operates at a different energy level, 60 minutes is a guideline only. Longer sonication time will not affect product quality. These precautions apply to working solutions prepared in your laboratory as well. The amount of compound that precipitates depends on concentration and temperature. If you store your standards, even dilute solutions, at a temperature well below the label recommendation, allow extra sonication time.

^‡In this standard, fluazinam should only be used for qualitative analysis.
