QUICK LINKS

Clavulanic acid potassium salt is a widely researched beta-lactamase inhibitor that has been a focal point in studies aiming to combat antibiotic resistance. In research environments, this compound is of particular interest due to its ability to inhibit a broad spectrum of beta-lactamases, enzymes produced by bacteria that render many antibiotics ineffective. Investigations involving clavulanic acid potassium salt delve into the structural and functional aspects of beta-lactamase inhibition, providing insights into how these enzymes interact with beta-lactam antibiotics and how inhibitors can enhance antibiotic efficacy. Additionally, it is employed in enzymology studies to understand the mechanism by which beta-lactamase inhibitors bind to their targets and protect antibiotics from degradation. This knowledge is for the design of new inhibitors that can be used in conjunction with antibiotics to overcome resistance. Moreover, the potassium salt form of clavulanic acid is particularly suited for such studies as it increases the compound′s solubility, making it more manageable in various experimental setups.

This is not dissolving in water. Why would this be happening and what can I do to help it go into solution?

Asked by: EDeak
Thank you for your question. This chemical, Clavulanic acid potassium salt: sc-207446, when dissolved in water will still maintain some microcrystalline cellulose (stabilizer) which can be filtered out, but it is not required to do so.

Relating to the former question, does cellulose added in this product affect purity? Our certification shows 98.2% as purity but chemical support described the ratio of cellulose to the clavulanic acid was 1:1....

Asked by: Microb
Thank you for your question. The product contains 50 mg stabalizer and 50 mg Clavulanate potassium, hence the 1:1 ratio. The purity is 98.2%.

I am unable to dissolve the chemical at 1 μg/ml, though the literature says this chemical can be dissolved at 300 mg/ml. What seems to be the problem?

Asked by: 13punMA
Thank you for asking about our product, Clavulanic Acid Potassium Salt (CAS# 61177-45-5). Clavulanate Potassium, the API for Q335 is soluble in water, but the product also contains an insoluble suspension called Microcrystalline Cellulose (AVICEL), which acts as a stabilizer.

I was unable to dissolve the product in a PBS with Methanol at a concentration of 256 mg/L. Can you help me understand what I am doing wrong?

Asked by: 13punMA
Thank you for asking about our product Clavulanic Acid Potassium Salt (CAS# 61177-45-5). I don't believe you are doing anything wrong. This particular product contains Microcrystalline Cellulose (AVICEL) 1:1, which acts like a stabilizer for the product. Although, the Clavulanate Acid Pottasium Salt is quite soluble in water, Microcrystalline Cellulose (AVICEL) is not. ​

Why exactly do you add the the stabilizer?

Asked by: 13punMA
Thank you for asking about our product Clavulanic Acid Potassium Salt (CAS# 61177-45-5). The reason why the stabilizer is added to the product is to protect the clavulanate, because it is sensitive to both moisture and heat.
