从China供应商批量进口5-Chlorovaleryl Chloride

Hebei Univtech Co., Ltd supplies 5-chlorovaleryl chloride, a bifunctional C5 acid chloride with terminal alkyl chloride and acyl chloride functionalities, molecular formula C5H8Cl2O. The listing identifies UN 3265 for hazardous material transport, Hazard Class 8 for corrosivity, a boiling point of 38-39 degrees Celsius at 0.15 mmHg, and a flash point of 90 degrees Celsius (195 degrees Fahrenheit). These parameters align with the compound's expected physicochemical profile, where low vapour pressure at room temperature coexists with substantial volatility under vacuum and moderate flammability risk at elevated temperatures. The 90 degrees Celsius flash point, while above common ambient temperatures, still classifies the material as combustible and relevant for storage insurance and facility zoning assessments.

The reactivity of 5-chlorovaleryl chloride derives from two electrophilic centres: the acyl chloride carbonyl carbon, susceptible to nucleophilic attack by amines, alcohols and enolates, and the primary alkyl chloride, which participates in substitution and elimination under appropriate conditions. This dual functionality enables synthetic strategies where sequential selective reactions build complex molecular architectures. The corrosive hazard classification reflects hydrolytic lability, moisture generating HCl gas and heat, a characteristic demanding rigorous anhydrous handling protocols. The 38-39 degrees Celsius boiling point under deep vacuum implies that standard rotary evaporation at water aspirator vacuum would be insufficient for concentration without thermal degradation, instead requiring oil pump or membrane pump capabilities for safe solvent stripping.

Pharmaceutical API synthesis and agrochemical active ingredient manufacture constitute the dominant end-use sectors for this material, with particular utility in linker chemistry for antibody-drug conjugates and in pro-agrochemical activation systems. Buyers typically include custom synthesis houses, generic API manufacturers, and agricultural science companies developing next-generation crop protection. Hebei Univtech Co., Ltd is located in Bazhou Economic District, Langfang, Hebei Province, a corridor with developing chemical manufacturing capacity between Beijing and Tianjin. The listing mentions flexible MOQ and CIF or FOB shipping options, but does not state specific quantities, packaging formats, or lead times, all of which require direct supplier confirmation before procurement finalisation.

Hebei Univtech Co., Ltd maintains its registered address at Bazhou Economic District, Langfang, Hebei Province, postal code 065700, China. The supplier classification shows 'imported' tier and 'harbor' trust tier, which are platform-derived designations indicating profile data ingestion without independent operational verification. The response rate is recorded at 0.00% with zero average response hours, meaning no historical buyer enquiry response data exists through the platform channel. This communication vacuum requires buyers to initiate contact through multiple methods, email, telephone and formal inquiry, to assess responsiveness before relying on this supplier for time-sensitive procurement.

No information is provided regarding the company's establishment date, ownership structure, number of employees, annual revenue, production facility size, or specific equipment for acid chloride manufacture. The source description references ISO and SGS certifications without certificate numbers, registration dates or scope of accreditation, making these claims unverifiable from the listing alone. Buyers should request scanned copies of current ISO 9001 and any relevant ISO 14001 certificates, plus SGS audit reports if available. The Bazhou Economic District location offers proximity to Beijing Capital International Airport and Tianjin Port for logistics, but geographic advantage must be balanced against due diligence on actual manufacturing capability versus pure trading activity.
