Against the backdrop of rapid expansion in fine chemicals, pharmaceutical APIs and edible flavor industries, aromatic aldehyde intermediates with consistent purity, controllable batch indicators and uninterrupted supply directly determine downstream manufacturers’ production efficiency and finished product quality. 4-Hydroxybenzaldehyde (CAS 123-08-0), also known as p-Hydroxybenzaldehyde, features dual active functional groups (hydroxyl and aldehyde). It serves as a core synthetic building block spanning four major sectors: pharmaceuticals, flavors & fragrances, agrochemicals and new materials. With years of expertise in aromatic aldehyde synthesis and self-owned eco-friendly production lines, Shanxi Yongjin Group Co., Ltd. has built a large-scale manufacturing base for high-purity 4-Hydroxybenzaldehyde, delivering one-stop raw material solutions for chemical purchasers worldwide.
Wide Application to Meet Demands of Multiple Industrial Chains
The unique molecular structure of 4-Hydroxybenzaldehyde delivers excellent reactivity, making it an irreplaceable fundamental fine chemical intermediate:
Pharmaceutical Manufacturing
It acts as a key upstream raw material for mainstream APIs including Amoxicillin, Trimethoprim (TMP), Esmolol and Gastrodin. It constructs molecular skeletons for antibacterial and cardiovascular medicines. High-purity grades greatly reduce side reactions and boost API yields, fully meeting strict purification requirements of pharmaceutical factories.
Flavors & Daily Chemicals
As an essential precursor to Vanillin, Ethyl Vanillin and Raspberry Ketone, it produces edible and cosmetic fragrances with pure aroma and long-lasting scent. Widely applied in bakery goods, beverages, perfumes and personal care products, it accounts for over half of the raw material demand from flavor manufacturers.
Agrochemicals
It is used to synthesize Bromoxynil and various low-toxic herbicides & fungicides, supporting the development of eco-friendly pesticides. Besides, it plays a vital role in manufacturing liquid crystal monomers, functional dyes, polymer resins and electroplating additives, covering nearly all fine chemical production scenarios.
Market demand keeps rising year by year, yet the industry faces widespread pain points: small workshops adopt outdated processes leading to fluctuating purity and excessive impurities that trigger rework for downstream clients; most manufacturers suffer limited capacity, resulting in stockouts and delayed deliveries during peak seasons; some suppliers fail waste treatment compliance, failing environmental audits for export; complete COA and MSDS documents are often unavailable, causing customs clearance obstacles for overseas shipments. Addressing these industrial challenges, Shanxi Yongjin Group eliminates procurement worries through large-scale self-developed production lines, standardized quality control systems and full-process export support.
Unmatched Factory Strength: Benchmark Manufacturer of Premium 4-Hydroxybenzaldehyde
Located in Hejin Economic & Technological Development Zone, Shanxi Yongjin Group is a Provincial Specialized & Sophisticated Enterprise and National High-Tech Enterprise specializing in R&D and production of aromatic aldehyde series. As our flagship mass-produced product, 4-Hydroxybenzaldehyde boasts competitive advantages as follows:
Self-developed Green Oxidation Synthesis Process with Graded Purity Control
We abandon highly polluted traditional synthesis routes and adopt low-by-product catalytic oxidation technology to drastically cut residues of heavy metals and phenolic impurities. Two mainstream grades are available:
Industrial Grade (≥99.0%): Suitable for general synthesis of pesticides and dyes
Pharmaceutical Refined Grade (≥99.5%): Stable melting point at 115–116℃ with uniform lump-free crystals, complying with stringent production standards for pharmaceuticals and high-end fragrances. Every batch undergoes HPLC testing with fully traceable transparent test data.
Standardized Self-owned Production Lines Ensure Stable Supply All Year Round
Equipped with dedicated synthesis workshops, independent precision QC laboratories and ten-thousand-ton comprehensive capacity for aromatic aldehydes, we maintain ample inventory at all times. Flexible supply caters to diverse order volumes:
Lab samples from 100g to 1kg for R&D trials
Regular shipments in standard 25kg fiber drums for mass production
Long-term fixed-price supply for ton-level bulk orders with consistent lead times in peak and off seasons, eliminating production shutdown risks caused by raw material shortages.
Full Compliance Support for Domestic & Overseas Sales
The company holds complete self-operated import and export qualifications, with closed-loop waste treatment systems in the factory. Our production complies with raw material regulatory standards of China, Europe, America and Southeast Asia. Complete supporting documents including COA, MSDS and customs clearance files are provided with each shipment, supporting procurement at exhibitions such as CPHI and cross-border chemical trade. Our products are exported to more than 20 countries across Europe, the Middle East and Southeast Asia, earning long-term stable partnerships with global clients.
Dedicated Technical Support Throughout Cooperation
Our professional chemical engineering team provides full technical backup: we adjust purification schemes tailored to clients’ downstream synthesis processes, offer guidance on storage, feeding and reaction parameters, and rapidly resolve after-sales issues concerning purity, packaging and logistics to cut clients’ operational and trial-and-error costs.
Standardized Storage & Transportation to Sustain Long-Term Product Quality
All products from Shanxi Yongjin Group are hermetically packed in 25kg fiber drums lined with PE film. Under cool, dry and dark storage conditions, the shelf life reaches 24 months, effectively preventing aldehyde oxidation and moisture-induced caking. We arrange full-truck and container dedicated logistics routes; export goods are reinforced with moisture-proof and anti-collision measures to guarantee intact delivery.
Conclusion
High-purity and stable 4-Hydroxybenzaldehyde lays the foundation for industrial upgrading for API manufacturers, flavor producers, agrochemical factories and new material research institutes. Adhering to the philosophy of “Green Production, Stable Quality, Long-Term Cooperation”, Shanxi Yongjin Group sells directly from the factory without middleman markups, balancing premium quality, competitive pricing and punctual delivery.
