Descrizione generale
Dehydroacetic acid is a pyrone derivative, that is typically synthesized by the base-catalyzed dimerization of diketene.[1] It is used as a preservative in pharmaceutical, food and cosmetic products.[2]
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.
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.
Applicazioni
Dehydroacetic acid may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical, food and cosmetic formulations by chromatography.[2][3][4][5]
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.
Risultati analitici
These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.
Altre note
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.
