Import 5-Hydroxy-2-Nitrobenzaldehyde — Buy in Bulk from Supplier in China

5-hydroxy-2-nitrobenzaldehyde (CAS 42454-06-8) is a nitro-substituted aromatic aldehyde with a hydroxyl group at the 5-position and a nitro group at the 2-position relative to the formyl substituent. Taixing Foreign Trade Nanjing Co. Ltd. supplies this compound as yellow crystalline material with a stated minimum purity of 98.0%, suitable for use as a pharmaceutical and agrochemical intermediate. The molecular formula is C7H5NO4, and the compound is typically handled under standard laboratory and industrial storage conditions to maintain stability. Buyers should confirm the exact particle size distribution and residual solvent profile with the supplier prior to committing to bulk orders, as these parameters affect downstream processing in synthesis workflows.

The 98.0% purity specification refers to assay by standard analytical methods, typically HPLC or titration, though the supplier does not specify the test method used. In pharmaceutical intermediate applications, typical additional specifications include maximum limits on related substances (often NMT 0.5% for any single impurity and NMT 1.0% total), moisture content by Karl Fischer (typically 0.5% w/w or less), and heavy metals content (often NMT 20 ppm). The nitro and hydroxyl functional groups make this compound reactive in electrophilic aromatic substitution, condensation, and reduction reactions commonly employed in active pharmaceutical ingredient (API) synthesis. Standard packaging for such intermediates is typically polyethylene-lined fiber drums or sealed polyethylene bags within cardboard containers, though the exact configuration from this supplier requires confirmation.

Primary applications span dye chemistry, pharmaceutical manufacturing, and agrochemical synthesis, where the compound serves as a building block for more complex molecules. Typical buyers include contract research organisations (CROs), generic API manufacturers, and specialty chemical distributors serving the life sciences sector. The supplier mentions flexible MOQ and trade terms including L/C and T/T payment, with FOB or CIF shipping options available. Given the zero percent response rate and harbor trust tier, buyers should initiate contact well in advance of planned production schedules and verify all specifications, lead times, and certificate of analysis (COA) availability directly with Taixing Foreign Trade Nanjing Co. Ltd. before transferring funds.

Taixing Foreign Trade Nanjing Co. Ltd. is based at 223rd North Zhongshan Road, Nanjing 210009, China, operating as a trading company with an imported supplier tier classification. The supplier holds a harbor trust tier and shows a zero percent response rate with zero average response hours recorded, which indicates limited verified engagement data is available through the platform profile. No information is provided regarding years in operation, factory ownership, production capacity, or specific quality management system certifications such as ISO 9001 or GMP compliance.

The company profile does not disclose employee headcount, annual revenue, named clients, or export market experience. The listing positions Taixing Foreign Trade Nanjing Co. Ltd. as a source of 5-hydroxy-2-nitrobenzaldehyde with flexible MOQ and standard payment terms, though all transactional details require direct negotiation. Buyers are advised to conduct full due diligence including verification of business registration, request of current COA, and clarification of whether the supplier operates as a manufacturer or distributor before relying on this source for critical supply chain needs.
