We manufacture over 1500 chemical intermediates including isothiocyanates, thioureas, amines, benzyl halides, carboxylic acids, nitriles, heterocycles and more.  Another aspect of our business has been providing researchers compounds which are not commercially available. We have custom manufactured hundreds of chemicals not listed in our catalog, in quantities ranging from grams to multi kilograms and have aided many companies with their pre pilot plant production needs.  All work is done in strict confidence and formal agreements are available when desired. We invite your inquiries and promise you will receive a prompt and reasonable quotation.  We manufacture over 95% of the products we sell, so as our customer you can be certain that you are paying the lowest price to be found.  We offer a 10% discount on all orders for 10 times the unit quantity specified.  In addition, substantial savings may be realized by ordering products in bulk quantities (30 or more units) and we will be glad to provide special quotations upon request.  The purity of our products is our most important consideration. Unless otherwise stated, all products have a minimum purity of 97%. Typical purities exceed this minimum and are most often in the range of 98% to analytically pure.
