See laboratory preparation below. Interested potential suppliers should submit an estimate detailing their proposed supply options. Sources are sought for potential suppliers to present supply options for the Government to review. Suppliers wishing to participate in this requirement must submit an estimate to IHDIV, NSWC by 20 June 2007, 4:00 p.m. Eastern Time. Attention: Karen Tindley, Code C12J. These Estimates should detail the following elements: (a) the basic technical specifications, including a copy of the MSDS if available, (b) the suppliers?? recommended storage/shipping conditions, (c) the suppliers?? delivery schedule, (d) the suppliers?? cost estimate. All estimates submitted under this request shall be considered Government property and treated as ??Competition Sensitive?? materials. If a contract is pursued in the future, the Government may select to negotiate for unlimited data rights for specification details. After a complete review of the estimates submitted under this request, the Government may choose to solicit contract proposals in June 2007. The estimates should be limited to not longer than three (3) pages and should highlight the following elements: (1) technical and administrative points of contact, (2) technical summary of chemical specification, (3) recommended chemical storage (4) recommended chemical shipment (5) delivery schedule, (6) cost estimate. Requirement Specification is as follows: >From Hawkins, Air Force Research Laboratory public released paper. (1) 1-Amino-3-methyl-1,2,3-triazolium iodide (C3H7N4I): 1-Amino-1,2,3-triazole 2.00 g (23.8 mmoles) was dissolved and stirred vigorously in 40 ml of acetonitrile at 20??C, whereupon methyl iodide 22.92 g (161.9 mmoles) was added. The reaction was stirred in darkness, being periodically monitored by thin layer chromatography until all amino-1,2,3-triazole was consumed. As the reaction progressed, white crystals of 1-amino-3-methyl-1,2,3 triazolium iodide precipitated. The product salt was collected by filtration and washed with several aliquots (50 ml total) of diethyl ether. The mother liquor was concentrated by distillation under reduced pressure resulting in a second crop of crystals that were collected by filtration, washed with diethyl ether combined with first crop and dried under high vacuum, resulting in a good yield 4.99 g (93%) of 1-amino-3-methyl-1,2,3-triazolium iodide. (2) 1-Amino-1,2,3-triazole (C2H4N4) In a 500 ml round bottomed flask, equipped with an over-head stirrer 14.46 g (168 mmoles) of glyoxal bishydrazone were dispersed in 225 ml of acetonitrile at 20 ??C. Manganese dioxide 30.00 g (348 mmoles), was added portion-wise over a few minutes to the vigorously stirred solution. The reaction was stirred for 40 minutes whereupon additional manganese dioxide 20.00 g (232 mmoles) was added. Thin layer chromatography revealed the reaction was complete 20 minutes later and it was filtered through a plug of Celite. The filtrate was stripped down under reduced pressure leaving a viscous oil, that was sublimed yielding 12.30 g (88%) of highly pure 1-amino-1,2,3-triazole. (3) Glyoxal Bishydrazone In a 2000 ml round bottomed flask, 510 g (15.94 moles) of anhydrous hydrazine were dissolved in 300 ml of methanol. Amount of 725 g (5 moles) 40% glyoxal solution in water were added over a period of three hours while keeping the reaction mixture at 0-10 ??C and white solid precipitated. After addition was completed, the flask was heated to about 80-90??C until all the solids dissolved. The flask was placed in the fridge over night and cold filtered. The solids were washed on the filter with isopropanol and dried in a vacuum oven. 354 g (4.1 moles, 82%) glyoxal bishydrazone were collected.
