A high-performance liquid chromatographic method has been developed for the simultaneous determination of chloroprocaine hydrochloride and its hydrolytic degradation product, 4-amino-2-chlorobenzoic acid. Separation is achieved using a mu-Bondapak C18 column and the eluant, water-acetonitrile-methanol-glacial acetic acid (74:20:5:1) containing 0.05-0.08% (w/v)

A sensitive and specific high-performance liquid chromatographic method for determination of the 2-chloroprocaine, local anesthetic of ester type, and its major metabolite 2-chloroaminobenzoic acid, has been developed and validated. A single-step extraction procedure is employed followed by high-performance liquid chromatographic
