A stability-indicating high-performance liquid chromatographic assay has been used to investigate the stability of solutions of melphalan under conditions that pertain to setting up in vitro chernosensitivity assays. Melphalan (1 and 20 pg/mL) was found to be 30% more stable in 150 mM NaCl solution

## Abstract Lightโscattering measurements have been carried out on carefully clarified aqueous solutions of pectin and pectic acid. The strong dependence of the inverse excess scattering intensity on angle yields pectin chain dimensions that are inconsistent with the complete molecular dispersion o
Multicurie amounts of propane-T, have been obobtained with typical yields of ca. 30% from the reaction of C3H8 with excess T2 over a Ni catalyst. The mass spectrometric analysis of the reaction product purified by preparative glc gave the following distribution: C3H8 16 mol%, C3H7T 13 mol%, C3HsT2 2
