3,4-Methylenedioxybenzaldehyde

Description

1. Product Overview

3,4-Methylenedioxybenzaldehyde (Piperonal) is a high-purity aromatic aldehyde characterized by a distinctive heliotrope-like scent, serving as a critical intermediate in pharmaceutical, agrochemical, and specialty fragrance synthesis. Its primary industrial application lies in the production of APIs (such as Tadalafil and L-DOPA intermediates) and high-value aroma chemicals. Strategically positioned at the nexus of fine chemistry and green synthesis, this molecule offers superior reaction specificity and yield efficiency, reducing downstream purification costs by up to 18–22% compared to substituted benzaldehydes. For global buyers, securing a reliable source of this compound is not a commodity purchase but a strategic hedge against supply chain volatility in regulated pharmaceutical feedstocks.

2. Key Specifications & Technical Characteristics

• Chemical composition: C₈H₆O₃ (1,3-Benzodioxole-5-carboxaldehyde); CAS RN 120-57-0

• Purity grade: Pharmaceutical grade (≥99.0% by GC) / Technical grade (≥98.0%)

• Physical characteristics:

  • Form: Crystalline powder or off-white to pale yellow flakes

  • Melting point: 35–37°C

  • Boiling point: 263°C (decomposes)

  • Density: 1.337 g/cm³ (20°C)

  • Particle size: 95% passing through 40 mesh (customizable)

• Packaging options: 25 kg fiber drums with inner PE liner / 500 kg polypropylene bulk bags / IBC totes (1,000 L)

• Shelf life: 24 months when stored below 30°C in airtight, light-resistant containers (inert gas purge recommended for >6 months storage)

3. Core Industrial Applications

• Pharmaceutical intermediates: Key synthon for the manufacture of phosphodiesterase-5 (PDE5) inhibitors and neuroprotective agents. Outperforms vanillin-based routes due to its fixed methylenedioxy ring, eliminating two protection/deprotection steps and reducing reaction time by 40%.

• Agrochemical synthesis: Precursor for piperonyl butoxide—a synergist that enhances pyrethroid insecticide efficacy by inhibiting pest metabolic enzymes. Its consistent isomer purity (≥99.0%) ensures batch-to-batch reproducibility, critical for EPA/EU compliance filings.

• Fragrance & flavor: Directly used as heliotropin in fine perfumery (floral-amber notes) and vanilla-like modifiers. Provides superior thermal stability (up to 200°C) versus synthetic vanillin, making it the preferred choice for high-temperature extrusion or candle applications.

• Electronics specialty chemicals: Intermediate for organic photoinitiators in PCB photoresists. Lower metal ion content (<5 ppm total) than standard grades reduces circuit defect rates.

4. Competitive Advantages

• Quality consistency: Statistical process control (SPC) with a CpK > 1.33 for purity and melting point; every batch includes HPLC and GC-MS chromatograms.
