Descripción general

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.

Aplicación

Guaiacol may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by high performance liquid chromatography (HPLC) and electroanalytical techniques.
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.

Acciones bioquímicas o fisiológicas

Guaiacol, along with 2,4,6-trichloroanisole, is responsible for cork taint in wine. A method has been developed for extraction and quantitation of the two compounds.

Nota de análisis

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

Otras notas

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
