“…The values of limiting molar conductance, Λ 0 , λ 0 (VHL + ), and K A for pyridoxine HCl have been reported earlier. 17 It has been observed that the K A value of the vitamin in DMSO is fairly high and that the pyridoxine cation is extensively solvated by DMSO as observed by the rapid decrease in the Walden product with increasing content of DMSO. 17 The conductometric data for the vitamin by steps 1-3 are given in Tables 1-4.…”

The complexation behavior of pyridoxine hydrochloride with certain oxa- and thia-crown ethers in dimethylsulfoxide has been studied by conductometric and polarographic techniques. The vitamin is observed to form complexes with six-membered coronand rings of the crown ethers. The conductivity studies indicate 1:1 complex formation between the vitamin and the crown ether. The nature of the atoms (oxygen and sulpur) in the coronand ring is observed to affect the stability of the complex. The limiting ionic conductivity of the complexed vitamin is also reported. In addition, complexation studies of pyridoxine hydrochloride were carried out by polarography, and the results obtained compared well with those obtained by conductivity measurements.
