d-methamphetamine

CAS RN: 537-46-2

Volatilization

A pKa of 9.87(1) indicates d-methamphetamine will exist almost entirely in the cation form at pH values of 5 to 9 and, therefore, volatilization from water or moist soil surfaces is not expected to be an important fate process(SRC). d-Methamphetamine is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 5.4X10-3 mm Hg(SRC), determined from a fragment constant method(2).
