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.
Betamethasone belongs to the corticosteriod family of active pharmaceutical ingredients (APIs). It exhibits anti-inflammatory activity and hence is used in the manufacture of various finished pharmaceutical products and is also employed as a starting material to manufacture other APIs that are related to this steroid family.

Application

Betamethasone may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations by using micellar liquid chromatography technique and reversed-phase high-performance liquid chromatography technique.
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

このような2次標準は、入手可能な場合にはUSP、EP、BPの1次標準にマルチトレーサビリティを提供します。

Other Notes

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.
