SPECIFIC TESTS
• Water Determination, Method Ia 921:
NMT 0.50%
• Limit of (R,R) Sertraline Hydrochloride
Mobile phase:
Hexane, 2-propanol, and diethylamine (960:40:1.5)
System suitability solution:
Transfer 10 mg of USP Sertraline Hydrochloride Racemic Mixture RS into a 20-mL volumetric flask. Add 4 mL of diluted ammonia water (1 in 10) and 10 mL of hexane. Shake well until the organic phase is clear. Wait for phase separation, transfer about 2.0 mL from the top layer into a 20-mL volumetric flask, and dilute with hexane to volume.
Standard solution:
Transfer 10 mg of USP Sertraline Hydrochloride RS into a 20-mL volumetric flask. Add 4 mL of diluted ammonia water (1 in 10) and 10 mL of hexane. Shake well until the organic phase is clear. Wait for phase separation, transfer 1.0 mL from the top layer into a 10-mL volumetric flask, and dilute with hexane to volume. Further dilute quantitatively and stepwise, if necessary, to obtain a solution having a known concentration of 0.01 mg/mL.
Sample solution:
Transfer 20 mg of Sertraline Hydrochloride to a 20-mL volumetric flask. Add 4 mL of diluted ammonia water (1 in 10) and 10 mL of hexane. Shake well until the organic phase is clear. Wait for phase separation, and use the top layer.
