Explanatory Notes

This volume gives detailed information on the hazardous properties of individual chemicals, either alone or in combination with other compounds. The items are arranged in order of the empirical formula (at right of second bold title line) which corresponds to the chemical name, or a synonym within parentheses, used as the first line bold title of each main entry; (nomenclature is now rather promiscuous since the systematisers have contrived to give many materials two or even three new names since the first edition was published, while the name used where chemicals are handled, as opposed to in lecture rooms, will be something else again). The 3 part number within square brackets at the left of the second title line is the CAS registry number, now being widely used to provide a reliable basis for establishing equivalence between differing chemical names and trade names for the same chemical compound (but note that one compound, within the terms of this work, may have numerous CAS numbers by virtue of isotopic composition, undefined stereo- and regio-chemistry or variant solvation levels). Lack of content within the square brackets indicates that a registry number has not yet been located, (or may not exist if CAS considers the compound insufficiently characterised, which is highly probable for materials which exploded during analysis) and (ion) after the number indicates that the main ion only has been located, rather than the specific title salt. Where possible, an alpahanumeric representation of...
