This is the most comprehensive collection of mass spectral data for steroids available today. It contains some 2,500 newly measured EI(+) mass spectra of androgens and estrogens and their derivatives (trimethylsilyl ethers, O-methyloximes and acetates). Each spectrum is accompanied by the structure, systematic and trivial names, retention index, molecular formula, molar mass, CAS number and sample source of the steroid, with all data obtained using the same mass spectrometer under identical chromatographic and mass spectrometric conditions.

Steroids are of considerable therapeutic importance, and the collection will thus be of particular interest to the pharmaceutical industry, as well as an invaluable data source for chemists and biochemists involved in drug development, drug screening and clinical toxicology, endocrinologists, natural products chemists and mass spectroscopists
