Product Overview

Vanillin 99.9% AR (CAS No. 121-33-5) is an aromatic aldehyde reagent whose phenolic, methoxy and aldehyde functionalities support characteristic colour-forming and derivatisation reactions. Vanillin-containing acidic spray or colour reagents are widely used to visualise suitable organic compounds after chromatographic separation, while its aldehyde group can also participate in analytical condensation reactions.

The AR grade is intended for analytical derivatisation, colour-reagent preparation, chromatographic visualisation and laboratory quality control. Its aromatic aldehyde functionality is particularly useful in condensation and colour-development reactions, including suitable TLC visualisation systems.

Typical Applications

• Preparation of vanillin-based TLC visualisation reagents.
• Analytical colour-development and derivatisation reactions.
• Preparation of non-certified vanillin working solutions.
• Spectrophotometric method development involving vanillin chemistry.
• Aldehyde-reaction and condensation studies.
• Laboratory QC of vanillin-based reagent systems.

Common Synonyms

• 4-Hydroxy-3-methoxybenzaldehyde
• 3-Methoxy-4-hydroxybenzaldehyde
• 2-Methoxy-4-formylphenol

Storage Conditions

Keep tightly closed, dry, and protected from prolonged exposure to strong light and air to minimise oxidation and discolouration. Use clean analytical handling to preserve reagent blanks.
