一般描述
Stearic acid is a saturated fatty acid, which is a long aliphatic chain containing a carboxyl group at one end and a methyl group at the other. Pharmaceutically, it is used as a lubricant in tablet and capsule formulations and as an emulsifying and solubilizing agent in topical formulations.
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.
应用
Stearic acid may be used as a pharmaceutical reference standard for the determination of the analyte in raw material, food and pharmaceutical formulations by gas chromatography.
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.
分析说明
These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.
其他说明
This Certified Reference Material (CRM) is produced and certified in accordance withISO 17034andISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
