What is the purity of this product?
This product is supplied at ≥99.9% 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.
How should this product be stored?
Store at room temperature, protected from light, 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?
The CAS Number is 5614-37-9, the molecular formula is C6H12O, and the molecular weight is 100.16 g/mol. InChIKey SKTCDJAMAYNROS-UHFFFAOYSA-N.
What documentation is provided?
Available product documentation, including Certificates of Analysis (COA), Safety Data Sheets (SDS), and specification sheets, is shown in the product document area. Document availability and access follow the current site policy.
