This database provides reference spectra for use in the chemical identification of unknown compounds. EPA-selected compounds pertinent to pollution and toxicological identification were contracted for this database. Each spectrum appears with the Chemicals Abstracts name, the molecular formula and weight, as well as the structural formula. Each compound is identified by its chemical name. All databases undergo the Sadtler Data Review Protocol to provide you with the highest standard available in spectral data today. These rigorous qualifying procedures start at data acquisition and continue throughout the database development process. All databases are tested in Sadtler laboratories by certified professionals with extensive training in spectroscopy and are validated by outside consultants. Every effort is made to maintain a high standard of accuracy before a spectrum can be placed in a collection.1.) Purity checked by another spectral technique. 2.) Chemical and physical properties listed. 3.) Chemical composition defined. 4.) Chemical structure included. 5.) Sampling technique listed. 6.) Databases created specifically for searching. 3,235 Spectra; Sadtler Product Code: 461000
