Table 3

Data derived from forced degradation study of TOL for the proposed LC method.

Condition	Time	% recovery TOL	Retention time of degradation products (minutes)
0.1 N NaOH^a	2 hrs	66.69	3.26, 3.91, 4.02
0.1 N HCl^a	24 hrs	85.70	4.03
3% H2O2^a	2 hrs	86.30	4.02
Dry heat^a	2 hrs	83.50	6.78
Sunlight	24 hrs	82.58	4.10, 4.63, 5.96

aSamples were heated at 80°C for specified period of time.
