✦ Synopsis

The average of five replicate determinations for percent intact melphalan in a single vial of dosage formulation was 88.7% with a standard deviation of 1 (range = 2.5 %).

Variations of less than 3 % were found in the assay of several vials from the same production lot. The samples and reference solutions may be used for quantitative work up to 24 hr. after preparation.
