Chloride Determination in Pharmaceuticals | Titration

Introduction

Chloride content in pharmaceutical formulations must be carefully controlled to ensure product quality, stability, and regulatory compliance. Excess chloride can affect formulation performance and may indicate contamination or process variability.

Potentiometric titration provides a precise and reliable method for determining chloride levels in pharmaceutical samples.

Analytical Challenge

Pharmaceutical formulations present several challenges for chloride analysis:

Complex sample matrices
Presence of interfering substances
Need for accurate low-level detection

These factors require a robust and selective analytical method.
