General description
Pharmaceutical secondary standards for application in
quality control, provide pharma laboratories and manufacturers with a
convenient and cost-effective alternative to the preparation of in-house
working standards.
Propylene glycol is commonly utilized as a penetration enhancer in topical
dermatological formulations, either alone or in combined form with other
penetration enhancing agents, like fatty acids.[1]
Application
Propylene glycol may be used as a pharmaceutical reference
standard for the determination of the analyte in pharmaceutical formulations by
chromatography techniques.[2][3][1]
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.
Analysis Note
These secondary standards offer multi-traceability to the
USP and EP (PhEur) primary standards, where they are available.
