o-Chlorobenzaldehyde FAQ
Frequently Asked Questions
Q: What is the shelf life of o-Chlorobenzaldehyde?
A: When stored properly in a cool, dry place away from direct sunlight and moisture, o-Chlorobenzaldehyde typically has a shelf life of 24 months. We recommend storing it at temperatures below 30°C in tightly sealed containers to prevent oxidation and maintain quality.
Q: What safety precautions should be taken when handling o-Chlorobenzaldehyde?
A: o-Chlorobenzaldehyde should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Ensure adequate ventilation in the working area as it may cause irritation to eyes, skin, and respiratory system. In case of contact, immediately flush with plenty of water and seek medical attention if irritation persists.
Q: Can o-Chlorobenzaldehyde be used directly for pharmaceutical synthesis?
A: Our standard grade o-Chlorobenzaldehyde is suitable for most industrial applications. For pharmaceutical synthesis, we offer an additional high-purity grade that meets pharmacopeia standards. Customers requiring pharmaceutical-grade material should specify this requirement when placing orders, as additional purification steps may be necessary.
Quality Assurance
Our o-Chlorobenzaldehyde undergoes rigorous quality control procedures:
| Test Parameter | Method | Specification |

Storage and Handling Recommendations
To maintain the quality of o-Chlorobenzaldehyde:
- Store in a cool, dry, well-ventilated area
- Keep containers tightly closed when not in use
- Protect from direct sunlight and heat sources
- Ground containers during transfer to prevent static discharge
- Use non-sparking tools when opening containers

o-Chlorobenzaldehyde FAQ (Continued)
Q: What is the typical lead time for o-Chlorobenzaldehyde orders?
A: For standard specifications, we generally maintain ready stock with a lead time of 3-5 business days for domestic orders. International shipments typically require 7-15 business days depending on destination and customs clearance. Custom specifications may require additional production time.
Q: How does o-Chlorobenzaldehyde differ from p-Chlorobenzaldehyde?
A: The key difference lies in the position of the chlorine substituent on the benzene ring. o-Chlorobenzaldehyde (ortho position) has different chemical reactivity and physical properties compared to p-Chlorobenzaldehyde (para position), making them suitable for different synthetic applications. The ortho substitution in o-Chlorobenzaldehyde often leads to steric effects in reactions.
Q: What documentation accompanies o-Chlorobenzaldehyde shipments?
A: Each shipment includes a Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS), and commercial invoice. Additional documentation such as TSCA certification, REACH compliance statements, or other regulatory documents can be provided upon request.
