Uses
Used in Biological Stains:
AZURE C is used as a biological stain for studying E. coli K30 bacterial polysaccharide. Its cationic nature allows it to interact with bacterial cells, providing a visual contrast for easier observation and analysis.
Used in Antifungal Applications:
AZURE C is used as an antifungal agent, particularly for studying the interactions between the dye and fungal cells. Its cationic properties enable it to disrupt the cell membrane of fungi, inhibiting their growth and providing a means to control fungal infections.
Used in Antibacterial Applications:
AZURE C is used as an antibacterial agent, particularly for studying the interactions between the dye and E. coli K30 bacterial polysaccharide. Its cationic nature allows it to interact with bacterial cells, inhibiting their growth and providing a means to control bacterial infections.
Purification Methods
Azure C has been twice recrystallised from H2O, and dried at 100o/1hour in an oven.
Check Digit Verification of cas no
The CAS Registry Mumber 531-57-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 531-57:
(5*5)+(4*3)+(3*1)+(2*5)+(1*7)=57
57 % 10 = 7
So 531-57-7 is a valid CAS Registry Number.

HPLC-MS and UV–Visible Coupled Analysis of Methylene Blue Photodegradation by Hydrothermally Grown ZnO Nanowires
Martin, Nathan,Leprince-Wang, Yamin
, (2021/10/27)
Photocatalysis is an efficient and promising method to purify water. Numerous studies have been dedicated to demonstrate its efficiency on several hazardous compounds, derived from various industries. However, even if the degradation of such products has been extensively studied, obtaining information on their photodegradation pathway is still challenging, leading to concerns about the innocuousness of the treated water. In this study, the authors use ZnO nanowires (ZnO NWs), to photodegrade a solution of the commonly used organic dye methylene blue (MB) under ultraviolet (UV) irradiation, followed simultaneously by UV-visible (UV-vis) spectrometry and high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS). Combining these two methods real-time information on the photodegradation efficiency and degradation mechanism are given. The HPLC-MS analysis allows us to confidently identify three reaction intermediates of the MB degradation: Azure A, B and C, as well as spot three other compounds, with uncertain formulas, leading to the presented hypothesis on the beginning of the MB degradation pathway. While the UV-visible analysis shows a total degradation of MB after 2 h of photodegradation, the HPLC-MS analysis indicates that some MB remain in the solution. Its quantity is calculated to be 14 μg L?1, which is harmless to humans.
