3,5-Dinitrosalicylic Acid Analytical Grade

The 3,5-Dinitrosalicylic Acid Analytical Grade by Dinâmica, available at LojaLab, is a nitroaromatic compound known by the abbreviations DNS or DNSA and used to prepare a colorimetric reagent for reducing sugars. In alkaline medium under heating, reducing substances convert part of the DNS into a colored amino-nitro product, producing an orange to reddish hue whose absorbance can be related to concentration through a calibration curve. The complete reagent normally contains additional components that control alkalinity, stability and color development.

Characteristics

• Nitroaromatic reagent also called DNS or DNSA
• Contains carboxyl, phenolic hydroxyl and two nitro groups
• Forms a colored product after reduction in alkaline medium under controlled heating
• Applied to reducing-sugar assays and hydrolytic-enzyme activity measurements
• CAS 609-99-4, formula C7H4N2O7 and molar mass 228.12 g/mol
• Colorimetric method depends on formulation, calibration curve, time and temperature.

Applications

• Preparation of DNS reagent for colorimetric determination of reducing sugars
• Indirect quantification of glucose, maltose and reducing equivalents using an appropriate curve
• Assessment of amylase, cellulase, xylanase and other glycosidase activities that release reducing sugars
• Monitoring hydrolysis of starch, cellulose and other carbohydrates in process studies
• Research on interferences, optimization and adaptation of the DNS assay to different matrices.
