Protocatechualdehyde

Protocatechualdehyde 99% Pure Powder – Premium Pharmaceutical Intermediate for Cardiovascular and Antioxidant Applications

Xi'an Le-Nutra Ingredients Inc. offers high purity Protocatechualdehyde (CAS 139-85-5) with ≥99% specification from our 60,000㎡ GMP compliant plant and annual capacity of 3,000 tonnes. This pale yellow to off white crystalline powder is a key pharmacological intermediary and bioactive chemical that occurs naturally in medicinal plants including Salvia miltiorrhiza and Coptis chinensis. Our product has a chemical formula of C7H6O3 and molecular weight of 138.12 4. It has excellent antioxidant efficiency, antiplatelet aggregation characteristics and neuroprotective advantages. Each batch is subjected to full testing for HPLC-DAD purity, heavy metals (ICP-MS) and microbiological content to fulfil international pharmacopoeia and to assure a steady supply for research of cardiovascular API, TCM quality control and synthesis of organic compounds.

What Makes Protocatechualdehyde Essential for Modern Pharmaceutical Development?

The substance, also known as 3,4-dihydroxybenzaldehyde, tackles major industry issues in pharmaceutical manufacture and natural product research. The twin hydroxyl groups on its benzene ring structure give greater radical scavenging ability, with IC50 values greatly surpassing Vitamin E in typical DPPH experiments.

This phenolic aldehyde passes the blood-brain barrier effectively, making it valuable for neuroprotective compositions. Its multi-pathway anti-inflammatory actions provide advantages over synthetic antioxidants in therapeutic applications.

Traditional Chinese medicine makers rely on this chemical as a reference standard for quality control and fingerprinting investigations. The compound's stability throughout industrial heating operations ensures consistent results in complex synthesis techniques.

Core Pharmacological Advantages

Benefits to Heart Health

Clinical studies have shown that it has considerable effects of anti-platelet aggregation and anti-myocardial ischaemia . These features contribute to the development of APIs for treatment of complex haemodynamic disorders and microcirculation improvement.

Improved Antioxidant Activity

The catechol structure is an analogue of DOPA with higher free radical scavenging activity. It stabilises compositions against oxidation generated by UV light in high-end dermatological products.

Mechanisms Of Neuro-protection

Its capacity to cross the brain barriers allows protective effects in neurological research. Its anti-inflammatory mechanisms further add to its benefit to the management of disorders associated to oxidative stress.

Standardisation of TCM

It is a chemical marker for traditional medicinal herbs, giving acceptable reference standards for quality assurance methods in the preparation of botanical extracts.

Industrial Applications Across Three High-Value Sectors

ProtocatechualdehydePharmaceutical Intermediate Synthesis

This Protocatechualdehyde molecule can be used to make compounds similar to adrenaline, antibiotics and antiviral drugs. The material presents a high thermal stability retaining the structural integrity for multi-step synthesis techniques.

API Research in Cardiovascular

It is of known biological action and is useful to researchers designing treatments for cardiac ischaemia and platelet aggregation disorders. The chemical is a research tool and a possible active ingredient.

Flavour and Perfume Chemistry

It is used as a vanillin precursor in flavour production and has melanin-inhibiting activity in dermatological formulations. The solubility profile makes it easy to include into complex formulation matrices.

Storage and Handling Best Practices

Proper storage prevents degradation of the catechol structure, which remains sensitive to photo-oxidation. Maintain airtight containers in cool, dry, well-ventilated areas at 2-8°C temperatures.

Protect containers from direct light exposure throughout the 24-month shelf life. Nitrogen-purged environments further extend stability for long-term research projects.

Avoid alkaline formulation environments where phenolic groups deprotonate and become susceptible to rapid oxidation. The melting point range of 150-157°C guides thermal processing parameters.

High-purity synthetic versions offer superior batch-to-batch consistency compared to natural extracts, though both forms remain chemically identical. Your application requirements determine the optimal sourcing strategy.

Packaging and Storage Specifications

Standard pharmaceutical-grade packaging utilizes 25kg fiber drums with dual-layer food-grade polyethylene protection. Research quantities ship in sealed aluminum foil bags preventing moisture ingress and light exposure.

All containers undergo leak testing before shipment. Labels include batch numbers, manufacturing dates, and storage instructions complying with GHS classification requirements.

Temperature-controlled logistics maintain cold chain integrity during international transit. We recommend immediate transfer to refrigerated storage upon receipt to preserve optimal stability throughout the shelf life.
