회사소개
Dear Sir,
I introduce myself as a manufacturer of fine chemicals. I had been working on the syntheses of synthetic organic and inorganic intermediates involving following types of reactions.
A,Oxidation,reduction,diazotisation,ammination,sulphonation,fluorination,bromination,chlorination,iodination,cyanation,alkylation,acylation and migration/rearragement etc.
B. Heterocyclic syntheses of the unsubstiteted/substituted moities of the classes of pyridine,pyrimidine,chromone,coumarin,isatin,indazole etc.
C. Multi-step synthesis of air/moisture/temperature sensitive compounds-eicosanoides,organic light emitting diodes(post-doc work).
With hands-on experience in the handling of above said reactions, i assure you the timely supply of quality products at competative prices.The following are some of the compounds which i had synthesised earlier. With my research and industrial experinece, i will prepare some other compounds in addition to the below listed compounds. For any other information, please feel free to contact us. Anticipating your kind co-operation and positive reply to build long-term business relation. future.
Thanking you for time and consideration.
With regards,
Dr Ramesh
Technical Director,RR Laboratories.
