Import 5-Chloromethyl-2 — Buy in Bulk from Supplier in China

5-chloromethyl-2 is a pharmaceutical intermediate supplied by Mabct Medicine from Shanghai, China, presented as a white or almost white powder with CAS number 252742-72-6. The compound carries a minimum purity of 98% as stated in the source data, which positions it for use in demanding synthesis routes where reproducible reactivity matters. Mabct Medicine operates from Zhangjiang High-Tech Park, a district with established chemical and pharmaceutical manufacturing infrastructure.

The powder form suggests milling to a defined particle size distribution, though the source does not specify D50 or D90 values; typical pharmaceutical intermediates of this class are handled under inert atmosphere where chloromethyl reactivity warrants moisture exclusion. The chloromethyl functional group confers electrophilic character, making this compound useful for N-alkylation or O-alkylation steps in API construction. Standard handling protocols for moisture-sensitive chloromethyl compounds apply: nitrogen-purged packaging, desiccant inclusion, and controlled humidity storage at or below 25 degrees Celsius.

Primary buyers include pharmaceutical manufacturers running multi-step synthesis programmes, contract research organisations building compound libraries, and agrochemical firms requiring halogenated building blocks. The supplier lists bulk supply availability without stating a fixed MOQ or lead time, so buyers should confirm minimum volumes and delivery schedules directly. Packaging is described as moisture-proof, a baseline requirement for hygroscopic or hydrolytically unstable intermediates; confirm whether double-layer polyethylene liners or aluminium-laminated bags are used.

Mabct Medicine is located at Room 813, No.780 Cailun Road, Zhangjiang High-Tech Park, Shanghai 201203, placing it within one of China's concentrated pharmaceutical and biotech development zones. The supplier carries an imported tier designation and a harbor trust tier, which indicates a basic marketplace presence without premium verification. Notably, the response rate is recorded at 0.00% with zero average response hours, signalling that enquiry response behaviour is untested or unmeasured rather than demonstrably poor.

The listing does not disclose manufacturing ownership (direct producer versus trader), facility accreditations, annual output, or staff scale. No ISO, GMP, or other certification numbers are provided in the source data. Buyers should therefore treat quality assurance as unverified and request a supplier questionnaire, quality agreement, and batch-specific certificate of analysis before committing to purchase. The address in Zhangjiang High-Tech Park suggests proximity to analytical service providers and logistics hubs, which may support faster technical clarification and sample turnaround if the supplier is responsive.
