Summary -- The CAS Registry Database
- Chemical structure
- Name -- via Substance identifer
- CAS Registry Number -- via Substance identifier
- Molecular formula
- Properties -- May be useful but do not rely on it
Substances -- Types
Substance roles -- Since 1966 (All years for Preparation)
Analyze by Precision
Analyze and Refine options
Preparations -- From SciFinder substance record
Retrieve references where substance's role is "Preparation"
Often best to look at oldest preparations first
Look for a preparation that meets your needs (e.g., scale, purity, convenience)
Some journals are specialize in synthesis (e.g., Organic Syntheses and Inorganic Syntheses)
Other “synthesis” journals include Synthesis and Synthetic Communications
Other chemistry journals such as the J. Am. Chem. Soc., Inorg. Chem. and J. Org. Chem.
SciFinder -- Reactions -- What is searched?
1985-present => Journals from Chemical Abstracts
1991-present => Patents from Chemical Abstracts
1974-1999 (Articles) and 1982-1999 (Patents) => VINITI (USSR) and ZIC (German) databases
1840-1985 => Core Reactions Database (INPI, French database)
1971-1997 => Biotransformations database
1921-pesent => Organic Reactions; Organic Syntheses; Encyclopedia of Reagents of Organic Synthesis
SciFinder -- Reactions -- Summary
Three ways to search for preparations.
- Explore substances ... choose references for Preparation <= This is the best
- Explore reactions ... use the reaction drawing window
- Explore references ... type in "preparation of [insert the CAS Registry Number]
