Terming Guidelines


FSN

Use the following pattern for the FSN. Groupers should be expressed in the singular. (Compound not compounds)

Example for substances that represent a structural grouper:

      • Organic nitrogen compound (substance)
      • Halide compound (substance)

      • Triazine derivative (substance)
      • Copper and/or copper compound (substance)
      • Phenothiazine and/or phenothiazine derivative (substance)
      • Nucleotide (substance)

Where the same word is used to identify both a group of substances with a particular chemical structure and a particular chemical substance the following terming for the FSN will be used for the substance grouper concept.
Substance with X structure (substance)

Examples:

      • Substance with tetracycline structure (substance)

      • Substance with cresol structure (substance)
      • Substance with benzene structure (substance)

Preferred Term

Use the following pattern for the Preferred Term, 

Example:

For example,

      • Organic nitrogen compound
      • Halide compound

      • Triazine derivative
      • Copper and/or copper compound
      • Phenothiazine and/or phenothioazine derivative
      • Nucleotide

Where the same word is used to identify both a group of substances with a particular chemical structure and a particular chemical substance the following pattern will be used for PT the substance grouper concept.

Substance with X structure

Examples:

For example,

      • Substance with tetracycline structure

      • Substance with cresol structure
      • Substance with benzene structure

Synonyms

A synonym to match the FSN must be created.

Additional synonyms are not allowed unless explicitly identified as an exception in the
