for solid packaged in single-unit containers: meets the requirements.

Diluent, Mobile phase, Standard preparation, and Chromatographic system— Prepare as directed in the Assay under Amoxicillin.

Assay preparation— Dilute an accurately measured volume of Amoxicillin for Oral Suspension, constituted as directed in the labeling, freshly mixed and free from air bubbles, quantitatively and stepwise in Diluent to obtain a solution containing about 1 mg of anhydrous amoxicillin per mL. Filter a portion of this solution through a suitable filter of 1-µm or finer porosity, and use the filtrate as the Assay preparation. Use this solution within 6 hours.

Procedure— Proceed as directed for Procedure in the Assay under Amoxicillin. Calculate the quantity, in mg, of amoxicillin (C16H19N3O5S) in each mL of the constituted Oral Suspension taken by the formula: in which L is the labeled quantity, in mg per mL, of anhydrous amoxicillin in the constituted Amoxicillin for Oral Suspension; D is the concentration, in mg per mL, of anhydrous amoxicillin in the Assay preparation on the basis of the labeled quantity in the constituted Amoxicillin for Oral Suspension and the extent of dilution; and the other terms are as defined therein.
