Frequently Asked Questions

What is the isotopic enrichment of this product?

This product is isotopically enriched to ≥98 atom% deuterium. Isotopic enrichment is a separate specification from chemical purity — a labelled compound has both. Lot-specific values are stated on the Certificate of Analysis.

What is Moligand??

Moligand? is one of Aladdin Scientific's premium product lines, formulated for high-purity applications across multiple workflows. Compared to standard grades in the same workflow, Moligand? products typically offer tighter specifications, more rigorous QC, and stronger lot-to-lot consistency.

How should this product be stored?

Store at room temperature, protected from light. The material is light-sensitive — keep it in its original opaque or amber container.

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 13010-53-2, the molecular formula is C5H11NO2S, and the molecular weight is 152.23 g/mol. InChIKey FFEARJCKVFRZRR-OSIBIXDNSA-N.
