Two spectrophotometric methods for the determination of ceftazidime (CFZM) in either pure form or in its pharmaceutical formulations are described. The first method is based on the reaction of 3-methylbenzothiazolin-2-one hydrazone (MBTH) with ceftazidime in the presence of ferric chloride in acidic medium. The resulting blue complex absorbs at lambdamax 628 nm. The second method describes the ...

BACKGROUND The heterocyclic hydrazones constitute an important class of biologically active drug molecules. The hydrazones have also been used as herbicides, insecticides, nematocides, redenticides, and plant growth regulators as well as plasticizers and stabilizers for polymers. The importance of the phenolic quinolyl hydrazones arises from incorporating the quinoline ring with the phenolic co...

In the title compound, C(15)H(13)FN(2)O(3)·CH(3)OH, the dihedral angle between the benzene rings of the benzohydrazone mol-ecule is 5.3 (3)°. The C atom of the meth-oxy group is almost coplanar with its attached ring [deviation = 0.017 (2) Å]. The r.m.s. deviation of the 21 non-H atoms of the hydrazone mol-ecule is 0.106 Å. In the crystal, the components are linked by O(m)-H⋯O(h), N(h)-H⋯O(m) a...
