从China供应商批量进口5-Chlorovaleric Acid, 1119-46-6

5-chlorovaleric acid (CAS 1119-46-6) is an omega-chlorinated carboxylic acid with molecular formula C5H9ClO2, commonly employed as a bifunctional building block in polymer science and pharmaceutical synthesis. Hebei Aoge Chemical Co., Ltd. supplies this material with a stated purity of 98%, positioning it for industrial applications where the terminal chloride and carboxylic acid group permit sequential derivatisation. The compound is a colourless to pale yellow liquid at ambient temperature with a characteristic acidic odour, though exact physical properties should be confirmed per batch.

The synthesis of 5-chlorovaleric acid typically proceeds via chlorination of valeric acid or hydrolysis of 5-chlorovaleronitrile, with the 98% grade indicating residual starting materials or formation of positional isomers such as 4-chlorovaleric acid. For polymer applications, the acid value and chloride content are critical parameters that determine chain extension efficiency in polyester or polyamide formation. The material's hygroscopic nature and acidity require storage in corrosion-resistant containers with low moisture permeability to prevent hydrolysis of the acid chloride impurity or acid-catalysed self-esterification.

Primary end-users include manufacturers of nylon-6 derivatives, where 5-chlorovaleric acid serves as a chain terminator or comonomer, and pharmaceutical producers synthesising pentapeptide analogues or gamma-aminobutyric acid derivatives. The 200 kg drum packaging mentioned by Hebei Aoge Chemical suits bulk chemical handling, though drum linings must resist acidic corrosion. Importers should confirm with the supplier the exact acid value, chloride titration result, and whether the material is supplied as a free acid or contains residual solvent from purification.

Hebei Aoge Chemical Co., Ltd. is located in Guantao New Chemical Industrial Park, Handan, Hebei Province, China. The company holds a Harbor trust tier, indicating basic platform verification. No response rate or average response time data is available, suggesting buyers should initiate contact through multiple channels and allow adequate time for reply. The industrial park location implies access to dedicated chemical infrastructure, including waste treatment and bulk storage, though specific facility accreditations are not listed.

The supplier profile does not disclose year of establishment, number of employees, annual turnover, or specific manufacturing capabilities. No certifications such as ISO 9001, ISO 14001, or Responsible Care are mentioned. Buyers should request a detailed company introduction, manufacturing licence for chlorinated acids, and environmental compliance records. The Handan region has significant chemical manufacturing density, which can support supply chain efficiency but also requires due diligence on environmental and safety compliance.
