从China供应商批量进口5-Chlorovaleryl Chloride

5-chlorovaleryl chloride from Handan Langtai Chem Co., Ltd. is an aliphatic acid chloride with the molecular formula C5H8Cl2O, commonly employed as an intermediate in organic synthesis. The supplier lists a minimum assay of 99.0%, which indicates the proportion of the target compound after standard analytical determination. The substance presents as a colourless, clear liquid at ambient conditions, a physical state typical for low-molecular-weight acid chlorides of this chain length. Its boiling point of 38-39 degrees Celsius at 0.15 mmHg reflects the compound's appreciable volatility under reduced pressure, a characteristic that demands vacuum distillation for purification and rotary evaporation for solvent removal in downstream processing.

The chemical structure contains a terminal chloro substituent on a five-carbon valeryl backbone, positioning it as a bifunctional building block: the acyl chloride moiety undergoes nucleophilic acyl substitution with amines, alcohols and thiols, while the alkyl chloride permits subsequent SN2 displacement or elimination. This dual reactivity profile makes it valuable in pharmaceutical intermediate synthesis, where it can serve as a masked linker for peptide coupling or as a precursor to lactam ring formation through intramolecular cyclisation. The 99.0% assay specification implies controlled manufacturing with minimised higher chlorinated or hydrolysed by-products, though buyers should request batch-specific certificates of analysis to confirm actual impurity profiles for critical applications.

Pharmaceutical manufacturers and agrochemical formulators represent the primary import audience for this material, using it to construct active pharmaceutical ingredient scaffolds or crop protection molecule cores. Academic research institutions with medicinal chemistry programmes also constitute a significant buyer segment. Handan Langtai Chem Co., Ltd. operates from Handan in Hebei Province, a region with established chemical industrial infrastructure. The listing indicates availability for bulk supply, but specific MOQ, packaging configurations, Incoterms and lead times are not stated and must be confirmed directly with the supplier before procurement planning.

Handan Langtai Chem Co., Ltd. is located at Chemical Industrial Estate, Handan, Hebei Province, postal code 056000, China. The supplier tier is marked as 'imported' and the trust tier as 'harbor', which are platform-assessed classifications indicating a baseline level of profile completeness rather than third-party verification of operational claims. The response rate is recorded at 0.00% with zero average response hours, signalling that this supplier has not engaged with buyer enquiries through the platform's messaging system. This absence of response data is a material consideration for buyers evaluating communication reliability.

The listing provides no information about the company's founding year, registered capital, production capacity, number of employees, or specific manufacturing equipment. No ISO, SGS or other certification numbers are supplied, despite generic references to 'international safety and quality standards' in the source description. Buyers should independently verify the supplier's business licence, hazardous chemical production licence, and export qualifications through direct due diligence. The chemical industrial estate location in Handan suggests access to Hebei's established chlor-alkali and fine chemical supply chain, but this geographic advantage does not substitute for facility audit or pre-shipment inspection.
