Preguntas frecuentes
What is the purity of this product, and how is it determined?
This product is supplied at ≥99.5% purity, determined by gas chromatography (GC). Lot-specific values are stated on the Certificate of Analysis.
How is this product shipped?
This product ships under standard ambient conditions. No temperature-controlled packaging is required.
What does Standard for GC mean?
Standard for GC indicates that the chemical has been purified and tested specifically for use in gas chromatography. Key specifications typically include controlled UV absorbance at common detection wavelengths, low non-volatile residue, controlled moisture content, and verified lot-to-lot consistency. Standard for GC is used for mobile phases, sample preparation and analytical standards in this workflow.
How should this product be stored?
Store at room temperature, desiccated. Keep the container tightly closed with desiccant — the material is moisture-sensitive.
What are the CAS number, molecular formula and molecular weight?
The CAS Number is 112-40-3, the molecular formula is C12H26, and the molecular weight is 170.33 g/mol. InChIKey SNRUBQQJIBEYMU-UHFFFAOYSA-N.
