Sec. 158.170  Preliminary analysis.

    (a) If the product is produced by an integrated system, the 
applicant must provide a preliminary analysis of each technical grade of 
active ingredient contained in the product to identify all impurities 
present at 0.1 percent or greater of the TGAI. The preliminary analysis 
should be conducted at the point in the production process after which 
no further chemical reactions designed to produce or purify the 
substance are intended.
    (b) Based on the preliminary analysis, a statement of the 
composition of the technical grade of active ingredient must be 
provided. If the technical grade of active ingredient cannot be 
isolated, a statement of the composition of the practical equivalent of 
the technical grade of active ingredient must be submitted.
