Product Overview

Benzaldehyde 98.5% Extra Pure (CAS No. 100-52-7) is the simplest aromatic aldehyde, consisting of a formyl group bonded directly to a phenyl ring. Conjugation between the carbonyl group and aromatic system influences its electrophilic behaviour, while the absence of an α-hydrogen directs its base-mediated chemistry towards characteristic pathways such as Cannizzaro disproportionation. Its accessible aldehyde functionality makes benzaldehyde a versatile parent substrate for carbon–carbon and carbon–nitrogen bond formation.

The Extra Pure grade is intended for routine organic synthesis, reaction development, catalyst evaluation, and general laboratory research requiring benzaldehyde of defined assay. It is suitable for condensation, nucleophilic-addition, oxidation, reduction, and imine-forming reactions used to prepare aromatic alcohols, acids, alkenes, imines, and other benzyl or benzoyl derivatives.

Typical Applications

• Preparation of benzoin through benzoin-condensation reactions.
• Carbon–carbon bond formation through Knoevenagel, Perkin, and crossed aldol-type condensations.
• Synthesis of imines and Schiff bases by condensation with primary amines.
• Nucleophilic-addition reactions with organometallic and other carbon nucleophiles.
• Preparation of benzyl alcohol and benzoic acid derivatives through controlled reduction or oxidation.
• Model aromatic aldehyde in carbonyl-reaction, catalyst-screening, selectivity, and reaction-mechanism studies.

Storage Conditions

Store in a tightly closed container in a cool, dark, and well-ventilated area. Protect from heat, ignition sources, prolonged exposure to air, and contamination. Close the container promptly after use, as environmental exposure can promote gradual oxidation and deterioration of the aldehyde reagent.
