In all instances, USP Reference Substance is specified. A number of variables can influence The steadiness with the reference standard alternatives. These include temperature, light-weight, oxygen, microbial decomposition, and adsorption into the container area. The developments of turbidity, added coloration, or effectiveness variability relative to freshly geared up options are indicators of instability.
Microbial Contamination: WFI should be sterile or have an exceptionally reduced microbial rely. Any microbial contamination could compromise the protection of pharmaceutical products, particularly those intended for injection.
