Abstract:
Methods of analyzing purity of compositions comprising cysteamine and detecting impurities in cysteamine compositions are described.

Claim (Index 3):
A method of analyzing purity of enteric-coated cysteamine beads comprising:\n (i) grinding enteric-coated cysteamine beads; (ii) dissolving the ground beads in a solvent having an acidic pH to form a sample solution comprising cysteamine; (iii) injecting the sample solution onto a reverse-phase HPLC column; (iv) eluting the sample from the column using a mobile phase comprising an alkyl sulfonic acid, a buffer, acetonitrile, and methanol; and (v) measuring the eluted sample using a UV detector at a wavelength of about 170 nm to about 250 nm.
