从China供应商批发进口5-Chlorovaleryl Chloride — FOB条款

Speranza Chemical Co., Ltd. supplies 5-chlorovaleryl chloride, a bifunctional building block with CAS number 1575-61-7 and molecular formula C5H8Cl2O. The supplier states a purity of 99 percent and a molecular weight of 155.02 g/mol. This liquid-phase acid chloride is used as a synthesis intermediate in pharmaceutical, agrochemical and specialty chemical manufacturing, where the terminal chloride and acid chloride groups enable sequential nucleophilic substitution and amidation reactions. The boiling point is given as 38-39 degrees Celsius at 0.15 mmHg, indicating high volatility under reduced pressure.

The compound is classified as Hazard Class 8 with UN number 3265 and packing group III, designating it as a corrosive liquid. It appears as a clear colorless to slightly yellow liquid at ambient conditions. Storage below plus 30 degrees Celsius is recommended by the supplier to maintain stability. Standard packaging is 200 kg per drum, though customer-specific packaging can be discussed. The dual functionality, five-carbon chain length and relatively low molecular weight make this intermediate suitable for introducing five-carbon spacers into active molecules or for polymer synthesis where controlled chain extension is required.

Buyers of 5-chlorovaleryl chloride typically include pharmaceutical contract research organisations, agrochemical formulators and fine chemical distributors seeking reliable supply of GMP or technical-grade intermediates. The acid chloride functionality requires careful handling to prevent hydrolysis, and the terminal chloride allows further functionalisation to amines, thiols or azides. Buyers should confirm with Speranza Chemical Co., Ltd. whether the stated 99 percent purity refers to GC area percent, assay by titration, or another analytical method, and whether batch-specific certificates of analysis are provided. Impurity profiles, residual solvent specifications and metal content should be requested for applications in regulated industries.

Speranza Chemical Co., Ltd. is headquartered at 1809 Yingfeng Center, No. 6 Yinwei Road, Longgang District, Shenzhen, 518000, Guangdong, China. The company holds a 'harbor' trust tier. The response rate is recorded as 0.00 percent with zero average response hours, meaning responsiveness metrics are either unavailable or not yet populated. Buyers should initiate direct contact to assess communication reliability and technical competency before committing to orders.

The supplier's profile does not disclose year of establishment, production capacity, reactor scale, number of employees, annual revenue, named customers or specific quality certifications such as ISO 9001 or GMP compliance. The listing positions Speranza Chemical Co., Ltd. as a supplier of fine chemicals and synthesis intermediates. Buyers should request a company profile, manufacturing site audit reports and regulatory compliance documentation relevant to their intended application.
