Import 4-Hydroxybenzaldehyde — Buy in Bulk from Supplier in China

4-Hydroxybenzaldehyde (CAS 123-08-0) is an aromatic aldehyde with a formyl group para-substituted to a phenolic hydroxyl, presenting as pale yellow to white crystalline solid with a characteristic bitter almond odour. Jiaxing Sunlong Industrial & Trading Co., Ltd. supplies this material as a chemical intermediate, though the listing lacks stated purity, manufacturing route, or batch analytical data. The compound has a molecular weight of 122.12 g/mol, melts at 115-118°C, and is a key building block for pharmaceutical active ingredients, vanillin derivatives, and organic synthesis pathways where the aldehyde functionality enables condensation, reduction, and oxidation chemistry.

Industrial production typically proceeds via Reimer-Tiemann formulation of phenol, oxidation of 4-methylbenzyl alcohol, or direct carbonylation routes, with purification by recrystallisation from water or ethanol to remove phenol, salicylaldehyde, and tarry by-products. Standard pharmaceutical-intermediate grade is ≥98.5% by GC or titrimetric assay, with tight limits on chloride (<0.05%), sulphate (<0.05%), and heavy metals (<20 ppm). The listing describes high purity and bulk supply without quantification, so buyers must obtain a current CoA specifying the manufacturing process, assay method, and impurity spectrum to assess suitability for regulated applications.

Principal demand comes from API manufacturers synthesising antihypertensives, antituberculars, and antiviral agents; fragrance houses producing lily-aldehyde analogues; and agrochemical formulators requiring intermediate structures for herbicide and fungicide synthesis. The compound's dual functionality (aldehyde and phenol) permits versatile derivatisation. For procurement from Jiaxing Sunlong, confirm the exact purity grade (pharmacopoeial, technical, or custom), packaging configuration (typically 25 kg drums with aluminium laminate liner for oxidation protection), moisture specification, and whether the material is manufactured in-house or sourced from a subcontracted facility. The zero response rate on the platform necessitates direct outreach to the Zhejiang address provided.

Jiaxing Sunlong Industrial & Trading Co., Ltd. is located at No.8 Youyi Road, Economic Development Zone, Jiaxing 314001, Zhejiang Province, China, placing it within the Yangtze River Delta chemical manufacturing corridor with access to Shanghai port infrastructure. The company is classified as an imported supplier with Harbor trust tier, but the listing provides no information on year of establishment, registered capital, employee count, production capacity, or in-house versus trading business model. The zero percent response rate and zero average response hours indicate no platform-mediated buyer engagement, which requires buyers to initiate contact through the disclosed physical address or independent directory sources.

The supplier's offering centres on 4-hydroxybenzaldehyde for pharmaceutical, fragrance, and specialty chemical end-uses, with claims of ISO and SGS compliance, bulk supply capability, and flexible MOQ. However, no certificate numbers, specific purity grades, actual MOQ figures, or lead times are present in the source data. The address in a designated economic development zone may confer tax or customs advantages, but buyers should verify the business licence scope (whether it includes chemical manufacture, trading, or both), any environmental compliance permits for aldehyde production, and whether the company holds API intermediate registration with any pharmacopoeial authority. Third-party audit or on-site inspection is advisable given the limited verifiable credentials in this profile.
