However, the content of the soft segment in binder, containing the
azide group, is generally higher to improve the energy performance of propellant, the hard segment hardly forms hard segment domain individually, which makes the structure and properties of this polyurethane are different from the general polyurethanes [14,15].
Sodium
azide was shown to form a variety of transformation products when interacting with the target analyte, atrazine, in both anaerobic and aerobic conditions (Ro et al.
sodium
azide (0.01% W/V) and thiomersal sodium (0.1% W/V) were added to the antigens as described by Hromatka and Adler, 1969.
Two different
azide core molecules were synthesized from optically active epoxy amine (12) (Figure 7).
The bis-bromoacetyl derivatives due to the influence of carbonyl group are more active in nucleophilic substitution reaction with nucleophiles including sodium
azide as compared with [alpha],[omega]-dibromoalkanes.
They were stimulated with recombinant human IL-2 (10 ng/ml), murine IL-4 (20ng/ml), IL-7 (10ng/ml), IL-9 (100ng/ml), IL-15 (100 ng/ml), IL-21 (100 ng/ml), or IL-6 (10 ng/ml; all from PeproTech) or stimulated in presence of sodium
azide (Sigma-Aldrich) in a 37[degrees]C or 4[degrees]C humidified incubator.
Reaction of furo[2,3-d][1,3]oxazinone 3 with sodium
azide in boiling acetic acid furnished two products separated by fractional crystallization: tetrazolylfuran derivative 10 which was crystallized from ethanol and furo [3,2-d] imidazolone derivative 11 which was crystallized from dioxane (Scheme 3).
The substituted naphthoquinones were reacted with sodium
azide in dimethylformamide and 2-arylthio-3-amino-1,4- naphthoquinone derivatives were obtained as the sole identifiable products except one cyclized compound.
Functional groups with click reactivity includes amine, sulfate, thiol, hydroxyl,
azide, alkyne, alkene and carboxyl groups.
The first generation of portable POC hemoglobin devices with single-use, dry reagent cuvettes operates based on a modification of Vanzetti's
azide methemoglobin method.
Another set of plants was placed in
azide sodium (2M) as a positive control, while for negative control, a set of A.
CTF, hydrogenation,
azide chemistry and phosgenation, high pressure reactions and handling halogens (CI/Br/I).
Aside from the perchlorates division, the company manufactures Halotron, a branded, clean fire extinguishing agent alternative to halon-based products and sodium
azide, a pharmaceutical chemical intermediate.
Twenty-four further contributions then cover materials including vinyl monomers, cannabis indica fibers, jute fibers, hydroxypropyl methylcellulose, oxidized regenerated cellulose, polyacrylamide, cellulose nanowhisker, and sulfonyl terminals; techniques such as
azide alkyne cycloaddition, gamma and electron beam irradiation, radical polymerization, UV grafting, self-assembly, and click chemistry; perspectives on the field in general including an assessment of progress in the field and characterization of copolymers; and applications such as toxin removal, antimicrobial activity, bleeding control, wound healing, intelligent response, and drug delivery.
