Application

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
Methylene Chloride may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by gas chromatography (GC) technique.

Analysis Note

These secondary standards offer multi-traceability to the USP and EP primary standards, where they are available.
