Analysis Note

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

Application

Chlortetracycline may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by spectrophotometry 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.

General description

Chlortetracycline Hydrochloride is a salt of chlortetracycline, which is a tetracycline which shows broad-spectrum antibiotic activity. It is generally used as a veterinary and aquaculture medicine. It is often used on dairy cattle and aquacultured catfish, salmon, and lobster.
Pharmaceutical secondary standard for application in quality control. Provides pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

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.
