Database synopsis: acd951

MDL Information Systems maintains the Available Chemicals Directory ^™, a large database of commercially available chemicals. It is designed to provides chemists with an efficient way to find supplier and pricing information for both research-grade and bulk chemicals.

The acd951 database contains:

• Generic and isomeric structures
• ACD numbers and CAS numbers
• Preferred names and catalog names
• Catalog information, e.g., supplier, price, purity, notes
• Jarvis-Patrick structural clustering
• Tautomer cross-referencing

"acd" (Available Chemicals Directory) was previously known as "fcd" (Fine Chemicals Directory).
