Perguntas frequentes

What is the purity of this product?

This product is supplied at ≥97% purity (chemical assay). Lot-specific values are stated on the Certificate of Analysis.

What does Anhydrous Grade mean?

Anhydrous Grade indicates that the material has been processed and tested for moisture-sensitive chemistry. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.

What does Basic-Grade Reagents mean?

Basic-Grade Reagents is a defined analytical purity tier suitable for general analytical and reagent applications. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. Basic-Grade Reagents is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.

How should this product be stored?

Store at room temperature.

How is this product shipped?

This product ships under standard ambient conditions. No temperature-controlled packaging is required.

What are the CAS number, molecular formula and molecular weight?
