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)
  
  

Use the following pattern for the Preferred Term, 

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:

• Substance with tetracycline structure

• Substance with cresol structure
  
• Substance with benzene structure
