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. Imipenem belongs to the class of carbapenems, a beta-lactam antibiotic, effective against aerobic and anaerobic bacteria. Carbapenems act by inhibiting the peptidoglycan synthesis involved in bacterial cell wall formation, thus causing the death of the target microorganism.


Imipenem may be used as a pharmaceutical reference standard for the quantification of the analyte in biological samples and pharmaceutical formulations by various analytical techniques.

Biochem/physiol Actions

Imipenem monohydrate is a broad spectrum B-lactam antibiotic. It is a member of the carbapenem class of "magic bullet" antibiotics for severe infections.

Analysis Note

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

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.
