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.
What does Animal Free mean?
Animal Free indicates that the material has been processed and tested for specialty industrial processing. 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 2–8 °C under argon. It is supplied under an argon blanket; reseal under inert gas after each use.
How is this product shipped?
This product ships chilled on wet ice. Unpack on arrival and transfer it to the storage condition stated above.
What are the CAS number, molecular formula and molecular weight?
The CAS Number is 52-90-4, the molecular formula is C3H7NO2S, and the molecular weight is 121.16 g/mol. InChIKey XUJNEKJLAYXESH-REOHCLBHSA-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.
