To 25 mL of RBF were added aldehyde (0.02 M),
thioglycolic acid (0.02 M), thiosemicarbazide (0.022 M), and 10 mL of concentrated [H.sub.2]S[O.sub.4].
The enhancement of Lu-CL reaction with cadmium telluride (CdTe) capped with
thioglycolic acid has been used for the determination of methionine (with oxidant IO4) [73] and phenacetin [74] and chrysoidine (with oxidant H2O2) [75].
After this preparation step, 0.1 mL of 2.5% sucrose and 0.1 mL
thioglycolic acid successively were add in the test tube containing 4 mL of 50% [H.sub.2]S[O.sub.4] keep in the water bach at 45[degrees]C to 50[degrees]C for 5 min and cool.
Then, 50 mg of AIR was dissolved in 5 ml of 2 N hydrochloric acid including 0.5 ml of 98%
thioglycolic acid and placed in hot bath (100[degrees]C) for 4 h.
In order to investigate the improved electrochemical properties of [Sb.sub.2][Se.sub.3] nanostructured materials, we report on a new low-cost fabrication method to dissolve the Se powder based on the mixed solvents of monoethanolamine and
thioglycolic acid at room temperature in air for the first time [15].
Bovine serum albumin, acrylamide, N,N'-methylene-bisacrylamide, trichloroacetic acid (TCA), FeS[O.sub.4], sulfuric acid, cumene hydroperoxide (CHP), butylhydroxy-toluene, methanol, xylenol orange, di-nitrophenylhydrazine (DNPH), guanidine, ethanol, ethyl acetate, hydrochloric acid, Coomassie[R] Brilliant Blue R-250,
thioglycolic acid, NBD-Cl, and o-phthalaldehyde (OPA) were purchased from Sigma-Aldrich (St.
A solution of halogenohydroxy substituted imines 1a-q (0.001 mole) in EtOH: 2-methoxyethanol (10mL: 10mL, v/v) containing anhydrous Zn[Cl.sub.2] (0.01 g) and
thioglycolic acid (0.001 mole) was refluxed for 6-8 hrs.
Other organic reagents for determination of niobium include 8-hydroxyquino- line-5-sulfonic acid [23] and
thioglycolic acid [24].
Copper sulfide nanoparticles, whose surface was modified with the organophilic compound of
thioglycolic acid, have been used in the polymeric bed in this research.
Here we introduce the one-pot synthesis of thiazolidinone from hydrazide (Scheme 2) with
thioglycolic acid, substituted aryl aldehydes in toluene using a Dean-Stark assembly to synthesized compounds 5a-5j (Scheme 2).
Cd [(C[H.sub.3]COO).sub.2]*2[H.sub.2]O (Aldrich, 99%), tetraethyl orthosilicate (TEOS) (98%),
thioglycolic acid (TGA) (98%), sodium hydroxide, polyoxyethylene octyl phenyl ether (TritonX-100), cyclohexane, n-hexanol, ethanol, and ammonium solution were purchased from Sigma-Aldrich.
Treatment of 4a-d with
thioglycolic acid in acetic acid under "silent" conditions resulted in cyclocondensation giving the corresponding thiazolidinone derivatives 7a-d.
