从China供应商批发进口3-Diaminoadamantane — FOB条款

3-diaminoadamantane, systematic name 1,3-diaminotricyclo[3.3.1.1(3,7)]decane with molecular formula C10H18N2, is a rigid tricyclic diamine supplied by Chongqing Maohuan Chemical Co., Ltd from their facility in Nan'an District, Chongqing. The compound features a cage-like adamantane core with primary amine functionality at the 1 and 3 positions, creating a fixed 1,3-relationship that enforces specific geometric constraints in coordination and polymer chemistry. It is described as a white solid, which is typical for purified diamine derivatives of this molecular class, and is offered for wholesale purchase with purity and batch-specific data to be confirmed directly with the supplier.

The dual amine groups permit difunctional reactivity: nucleophilic attack on activated carbonyls, Schiff base formation, urea/thiourea synthesis, and metal chelation for catalyst precursors. The adamantane cage imparts lipophilicity and metabolic stability valued in pharmaceutical lead optimisation, while the rigid backbone reduces conformational entropy penalty upon binding to biological targets. In materials science, the compound serves as a hard segment precursor for polyureas and polyamides, and as a crosslinking agent for epoxy systems where thermal and chemical resistance are required. Typical purity grades for pharmaceutical intermediate use range from 95 percent to above 98 percent by area percent HPLC, with custom purification to 99 percent plus available from specialty suppliers on request.

Primary demand comes from contract research organisations, generic API manufacturers, and academic groups pursuing heterocyclic scaffold diversification. The compound is traded in gram to kilogram quantities, with larger batches requiring longer lead times due to multi-step synthesis from adamantane or 1,3-dibromoadamantane precursors. Chongqing Maohuan lists this as a wholesale product, though exact MOQ, pricing, and lead time are not disclosed in the source. Buyers should request a current certificate of analysis, safety data sheet, and stability data before placing orders, particularly for regulated market applications where impurity profiling and residual solvent specifications are mandatory.

Chongqing Maohuan Chemical Co., Ltd is located in Nan'an District, Chongqing 400063, China, operating within one of China's major inland chemical manufacturing hubs with access to the Yangtze River port system. The company holds an imported supplier tier and harbor trust tier on the platform, with a response rate of 0.00 percent and zero recorded average response hours, indicating no buyer engagement tracked through this channel. The supplier profile does not state year of establishment, number of employees, annual revenue, GMP certification, ISO accreditation, or named pharmaceutical client relationships.

The listing positions 3-diaminoadamantane as a wholesale specialty chemical without disclosing production scale, reactor capacity, or whether synthesis is performed in-house or sourced from contracted manufacturers. No quality management system certifications, DMF numbers, or regulatory filings are mentioned. Buyers should conduct independent due diligence including verification of business licence, chemical production licence, and environmental compliance status before advancing purchase negotiations, particularly for export orders requiring hazardous material documentation.
