Uses
1. Used in Analytical Chemistry:
N-(9-Acridinyl)maleimide is used as a reagent for the fluorescent labeling of thiols, sulfides, and sulfites. This application is crucial for the determination of these species by high-performance liquid chromatography (HPLC), which is a widely used technique for the separation and analysis of various compounds in complex mixtures.
2. Used in Food and Fermentation Industry:
In the food and fermentation industry, N-(9-Acridinyl)maleimide is utilized for the fluorometric determination of sulfites in products. Sulfites are commonly used as additives in the food and beverage industry for their antimicrobial and antioxidant properties. However, their presence in certain products can cause health issues, particularly for individuals with sulfite allergies. The use of N-(9-Acridinyl)maleimide allows for the accurate measurement and monitoring of sulfite levels, ensuring product safety and compliance with regulatory standards.
3. Used in Environmental and Industrial Applications:
Similar to its use in the food and fermentation industry, N-(9-Acridinyl)maleimide is also employed for the fluorometric determination of sulfites in environmental and industrial samples. This is important for monitoring and controlling the release of sulfites into the environment, as well as ensuring the safety and quality of industrial products that may contain sulfites.
Purification Methods
Purify NAM by chromatography on silica gel using CH2Cl2 as eluant. Evaporation of pooled fractions that gave the correct NMR spectra gave a solid which was crystallised from Me2CO as pale yellow prisms. IR max (nujol): 1710 (imide); UV (MeOH): max (nm), ( 1cm-1): 251 (159 500), 343 shoulder (7 700), 360 (12 400) and 382shoulder (47 000). [Mashida et al.

Check Digit Verification of cas no
The CAS Registry Mumber 49759-20-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,5 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 49759-20:
(7*4)+(6*9)+(5*7)+(4*5)+(3*9)+(2*2)+(1*0)=168
168 % 10 = 8
So 49759-20-8 is a valid CAS Registry Number.
