The microdetermination of ascorbic acid with N-chlorosuccinimide

Area of Science:

• Analytical Chemistry
• Biochemistry

Background:

• Ascorbic acid (vitamin C) is a vital nutrient with diverse biological roles.
• Accurate microdetermination of ascorbic acid is crucial for clinical diagnostics and nutritional analysis.

Purpose of the Study:

• To develop and validate novel, simple, and rapid methods for the microdetermination of ascorbic acid.
• To investigate the reaction mechanism between N-chlorosuccinimide and ascorbic acid under various pH conditions.

Main Methods:

• Three new quantitative methods for ascorbic acid analysis were developed.
• The methods utilize N-chlorosuccinimide as an oxidizing agent in acidic, alkaline, and neutral media.
• Reaction mechanisms were elucidated to understand the chemical basis of the assay.

Main Results:

• The proposed methods allow for the accurate microdetermination of ascorbic acid down to 10 micrograms.
• Experimental errors were found to be within +/- 2% for pure solutions.
• The methods demonstrated good accuracy (within +/- 5% error) when applied to biological fluids (blood, urine) and edible fruits.

Conclusions:

• The developed N-chlorosuccinimide-based methods offer a reliable and efficient approach for ascorbic acid quantification.
• These methods are suitable for routine analysis in both laboratory settings and for biological sample matrices.
• The simplicity and accuracy make these methods valuable for nutritional and clinical assessments.
