从China供应商批发进口3,5-Dihydroxybenzaldehyde — FOB条款

3,5-Dihydroxybenzaldehyde is an aromatic aldehyde with the molecular formula C7H6O3, featuring two hydroxyl groups at the 3 and 5 positions relative to the formyl group at position 1. This substitution pattern places it within the resorcinol-aldehyde family, compounds valued for their reactivity in condensation reactions and metal chelation. The compound serves as a versatile synthon in pharmaceutical chemistry, where the aldehyde group undergoes standard carbonyl chemistry while the phenolic hydroxyls provide additional functional handles for further derivatisation. Chinese production of this intermediate concentrates in Hubei Province, where established fine chemical clusters support both laboratory-scale and multi-tonne manufacture.

The material is typically supplied as an off-white to pale beige crystalline powder with a characteristic phenolic odour. Industrial grades range from technical (approximately 98% purity) to reagent grade (99% or higher), with the appropriate grade selected based on end-use sensitivity to impurities. The melting point, a critical identity test for this solid, typically falls between 240-245 degrees Celsius with decomposition, though exact values depend on crystalline form and heating rate. For long-term storage, the compound requires protection from light, air, and moisture, as the aldehyde group is prone to oxidation to the corresponding carboxylic acid and the phenolic hydroxyls can undergo oxidative coupling under basic conditions. Standard packaging includes fibre drums with polyethylene liner bags or aluminium-laminated pouches for smaller quantities, with desiccant included to control moisture uptake during repeated opening.

Fragrance and flavour houses utilise 3,5-Dihydroxybenzaldehyde as a precursor to vanillin analogues and other aromatic aldehydes with modified sensory profiles. Pharmaceutical manufacturers employ it in syntheses targeting anti-infective and anti-inflammatory compounds, while specialty dye producers value its dialdehyde-reactive chemistry for colourant development. The compound's dual hydroxyl pattern also makes it useful in polymer cross-linking applications and as a ligand in coordination chemistry. Buyers should confirm the specific purity grade, melting point range, and packaging format with Wuhan Yuan Cheng GongChuang Technology Co.Ltd before finalising purchase, as these parameters vary significantly between technical and fine chemical specifications.

Wuhan Yuan Cheng GongChuang Technology Co.Ltd is headquartered at Qianjiajie, Wuhan, Hubei Province, 432000, China. The company holds a Harbor trust tier, the baseline verification level on the marketplace. The response rate is recorded at 0.00% with zero average response hours, indicating no engagement with buyer inquiries through the platform's communication system. The available profile contains no information about year of establishment, facility size, annual turnover, number of employees, or manufacturing versus trading-only business model.

The supplier's listing positions 3,5-Dihydroxybenzaldehyde for pharmaceutical, chemical, and cosmetic industry applications without specifying production capacity, stock levels, or custom synthesis capabilities. The profile mentions ISO certification without identifying the certifying body, scope, or certificate number. Buyers should independently verify all quality claims, particularly the stated ISO compliance, by requesting certificate copies. The Wuhan location places this supplier within one of China's major fine chemical and pharmaceutical research clusters, which provides regional sourcing advantages but does not guarantee any particular quality standard from this specific company.
