How to find the right Organic Reagents AI guide

Written by an AI model from its trained knowledge.

What the AI looks for in Organic Reagents

Confirm identity by CAS number
Match the CAS number and structure, not just the name. Isomers and salt forms share similar names.
Assay method
Check how purity was measured (GC, HPLC, NMR or titration) and the stated value on the lot CoA. Different methods miss different impurities.
Stereochemical purity
For chiral reagents, look for a stated enantiomeric excess or optical rotation. The wrong enantiomer or a racemate ruins asymmetric work.
Stability and storage
Follow the stated storage temperature, stabilizers and inert packaging for air- or moisture-sensitive reagents. Many organic reagents degrade, polymerize or hydrolyze.

Brands that matter

  • TCI: Broad organic catalog with strong purity documentation.
  • Sigma-Aldrich (MilliporeSigma): Largest organic reagent catalog.
  • Thermo Scientific Chemicals: Former Acros Organics and Alfa Aesar organics.
  • Oakwood Chemical: Building blocks and fine organics.
  • Combi-Blocks: Medicinal chemistry building blocks.
  • Ambeed: Building blocks and intermediates.

What to avoid

  • Listings without a CAS number or lot CoA
  • Air-sensitive reagents shipped without inert packaging
  • Assuming a 'tech grade' organic is fine for kinetics or analysis
