克拉霉素

克拉霉素是一种大环内酯类抗生素，能干扰细菌蛋白质的合成。克拉霉素是红霉素的酸稳定形式，对革兰氏阴性细菌特别有效。它的半衰期很短，但是其代谢产物 14-羟基克拉霉素对某些细菌的活性几乎是克拉霉素的两倍。

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

Clarithromycin may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by ultra-performance liquid chromatography (UPLC), high performance liquid chromatography (HPLC) and time-of-flight-secondary ion mass spectrometry (ToF-SIMS) techniques. It can be used as a reference standard in validating the concentration of clarithromycin in human plasma samples using liquid chromatography coupled with tandem mass spectrometry (LC-MS-MS). Clarithromycin may also be used as a test reference standard to validate and compare its purity using two different types of methods, quantitative nuclear magnetic resonance (qNMR) and high performance liquid chromatography (HPLC).
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.

Clarithromycin belongs to the group of macrolide erythromycin antibiotics. Owing to its broad-spectrum antibacterial activity, several dosage forms of clarithromycin have been formulated. It is widely utilized to treat the infections caused by Chlamydia, Mycoplasma, Legionella, Helicobacter pylori, and Mycobacterium avium complex. It is also known to be active against HIV-related opportunistic infections.

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.
