INTRODUCTION

Any analyst who encounters for the first time a new procedure for determining heavy

metals may well feel baffled if he is advised to carry out a titration in a urotropinebuffer with complexon IV using sulfarsazen as an indicator. How should he proceedwhen recommended to carry out a liquid-liquid extraction with a solution of Aliquat-336in hexone or IBMK after adding BAL as a masking agent? How does he find out whetherCalcion is the same as Calcichrome, or Erio T the same as Solochrome Black WDFA; whetherthere is a significant difference between MBTh and MBII-JA, between Magneson I and MagnesonII, or between Titan Yellow and Clayton's Yellow?

The following list of trivial names and synonyms has been produced with theseproblems in mind. It is certainly not exhaustive. Acid-alkali indicators have beenomitted and of the numerous commercial and synthetic dyestuffs only those frequentlyreferred to in papers dealing with complexometric titrations have been included. Thesame restriction applies to the many tetrazolium salts used as redox indicators and to

which trivial names have been given. Organic scintillators, ion-exchange resins, stains,and reagents specifically used in biochemical procedures are not included.

When more than one trivial name or synonym is used for a particular substance, allalternatives are given without any proposed preference. The list that follows isintended only as a guide to identifying the chemical composition of substances used inanalytical chemistry, and is not to be taken as implying IUPAC approval or recommendationfor the names themselves, nor as modes for naming other analogous compounds.

The collection of material for this report was begun by R. W. Fennell in 1965 andcontinued by members of Commission V.3 and Professor H. M. N. H. Irving who isresponsible for the present report. Special thanks are due to Dr. K. L. Loening of theAmerican Uiemical Society, chemical Abstracts Service, for his careful checks on thecorrectness and consistency of the organic nomenclature and for many valuable comments.
