Frequently Asked Questions

What does ACS mean?

ACS 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. ACS 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 under argon. It is supplied under an argon blanket; reseal under inert gas after each use.

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?
