4-hydroxybenzaldehyde with cas 123-08-0
4-Hydroxybenzaldehyde (abbreviated as PHBA), is a colorless to slightly yellow crystalline powder. It contains both phenolic hydroxyl group (-OH) and aldehyde group (-CHO) on the benzene ring, which are dual active functional groups. It has high reactivity and is an extremely important aromatic fine chemical intermediate. It is widely used in the synthesis of medicines, fragrances, pesticides, and liquid crystal materials.

Feature
1. The dual-active functional groups (phenolic hydroxyl group + aldehyde group) have abundant reaction sites and multiple downstream synthesis routes. They are highly versatile aromatic intermediates in fine chemicals, capable of extending multiple industrial chains such as pharmaceuticals, flavors, and liquid crystals.
2. Complete purity gradients: industrial grade 99.0%, refined grade 99.5%, high-purity 99.9%; low moisture, low heavy metals, low impurities, meeting strict indicators for pharmaceuticals and electronics, with good batch stability.
3. Excellent physical and chemical properties: it can sublime, easily soluble in organic solvents such as ethanol, acetone, and ethyl acetate; the melting point is stable at 114–118℃, facilitating crystallization purification and downstream reaction control.
4. High downstream conversion rate, few by-products, high customer synthesis yield, reducing production losses for customers.
5. Stable supply, large-scale mass production, customizable indicators.

FAQ
Q: How should the packaging be stored after opening?
A: Use it all at once as soon as it is opened; keep the remaining materials sealed, isolate from air, store in a dark place, and avoid damp conditions; minimize repeated opening.
Q: What points should be noted in the synthesis reaction?
A: Phenolic hydroxyl groups will form salts when exposed to strong bases; aldehyde groups are prone to oxidation, so the reaction system should be isolated from oxygen; possible reactions include condensation, methylation, and redox reactions; avoid storing with strong oxidants and strong acids and bases; keep away from heat sources.
Q: Storage conditions?
A: Seal, store in a cool, dry, and dark place; keep away from strong oxidants, strong acids and bases; keep away from heat sources. The packaging is a 25kg inner PE bag cardboard barrel.
Q: Sample policy?
A: Charge a sample fee; the sample fee can be refunded after placing a large order.
Sample delivery time: Prepare 1-3 working days based on inventory, international delivery takes 3-7 days (depending on the destination country).
Q: Delivery time for large orders?
A: Standard ≥ 99.0% industrial grade ready stock: 7-12 working days after receiving the deposit.
Packaging: 25kg inner PE bag cardboard barrel.
