从China供应商批量进口3-Hydroxycinnamic Acid

3-Hydroxycinnamic acid, also referred to as 3-Coumaric acid, is a hydroxycinnamic acid derivative with the molecular formula C9H8O3 and a molecular weight of 164.16 g/mol. This compound features a phenolic hydroxyl group at the 3-position of the cinnamic acid backbone, which confers distinct reactivity patterns compared to its 4-hydroxy and 2-hydroxy analogues. Yuancheng Pharmaceutical Co., Ltd. lists this material as an antioxidant active suitable for pharmaceutical and nutraceutical formulation, with supply originating from their facility at 496 Zhongshan Road, Wuhan, Hubei province. The compound is typically supplied as a crystalline solid with documented solubility in ethanol, methanol, and aqueous alkaline solutions.

The material grade offered is consistent with pharmaceutical intermediate standards, though buyers should request a Certificate of Analysis to confirm batch-specific purity, residual solvent content, and microbial limits. 3-Hydroxycinnamic acid occurs naturally in plant sources including coffee beans, apples, and various cereals, though commercial supply is predominantly synthetic or semi-synthetic. The trans-isomer predominates in commercial material and exhibits superior stability compared to the cis-form. Typical manufacturing routes involve Perkin condensation of 3-hydroxybenzaldehyde with malonic acid, followed by decarboxylation and recrystallisation. Storage under inert atmosphere at 2-8 degrees Celsius is standard to prevent oxidative degradation of the conjugated double bond system.

Primary applications span dietary supplement formulation as an antioxidant compound, cosmetic formulations targeting free-radical scavenging, and food additive applications where regulatory approval permits. Pharmaceutical researchers utilise the compound in prodrug development and as a building block for more complex therapeutic molecules. The phenolic structure enables participation in enzymatic esterification for improved bioavailability in oral dosage forms. Buyers should confirm with Yuancheng Pharmaceutical Co., Ltd. the specific grade offered, intended application suitability, and whether the material is accompanied by regulatory documentation such as a Drug Master File or food-grade safety assessment.

Yuancheng Pharmaceutical Co., Ltd. operates from 496 Zhongshan Road, Wuhan 430064, Hubei province, China. The supplier is classified under the imported tier with a harbor trust tier designation. The response rate is recorded at 0.00 percent with an average response time of zero hours, which indicates that direct inquiry may be necessary to establish communication channels. The listing does not provide information about factory certification, years in operation, employee count, annual revenue, or specific quality management systems in place. Buyers should treat the lack of response data as a signal to conduct additional due diligence before committing to orders.

The company positions itself as a supplier of 3-Hydroxycinnamic acid for industrial and pharmaceutical applications, with availability in bulk quantities. The source description mentions flexible minimum order quantities and competitive pricing, though no figures are stated. The listing references FOB and CIF Incoterms as available options, and notes efficient packaging and shipping without specifying carriers or standard lead times. No client references, export history, or specific regulatory registrations are disclosed. Buyers should request a company profile, quality manual, and recent audit reports to assess capability against their own supplier qualification criteria.
