1H-Benzotriazole

In the title compound, C(6)H(5)N(3)O·C(13)H(11)N(3)O, the benzo-triazole ring system in the 1-benzyl-1H-benzotriazole 3-oxide (A) mol-ecule is close to being planar (r.m.s. deviation = 0.011 Å); its mean plane forms a dihedral angle of 67.56 (7)° with that of the attached phenyl ring. The benzotriazole ring system in the 1-hy-droxy-benzotriazole (B) mol-ecule is also close to being planar (r.m.s. deviation = 0.010 Å). In the crystal, weak C-H⋯O and C-H⋯π inter-actions are present. The A and B molecules are linked by an O-H⋯N hydrogen bond.

What is Etidronic acid

Etidronic (etidronate disodium) has a new authorized indication for the prevention of bone loss due to corticosteroid therapy. Three randomized, double-blind, placebo-controlled trials were conducted in this setting. The benefits of etidronics were based solely on lumbar BMD (a surrogate endpoint) and showed that in women. There is no concrete evidence that etidronic is more effective than placebo in reducing the risk of fracture in patients with corticosteroids. Similarly, in the absence of comparative trials are not evidence that etidronic is more effective than hormone replacement therapy in postmenopausal women.

Determination of myclobutanil 25% WG degradation dynamics in ginseng root

High-performance liquid chromatography coupled with a tandem mass spectrometry (HPLC / MS) method was developed 25% WG in ginseng root, stem, leaves and soil to determine kinetics Of degradation and the endreste of myclobutanil. The samples were extracted with purified acetonitrile with secondary amine primer (PSA) attached to the phase extraction cartridge by Kromasil Eternity-5-C18 (2.1 mm x 150 mm, 5 microm) of The column with a gradient of acetonitrile and 0.1% of formate separated in water as a mobile phase and analyzed at the multiple reaction monitoring (MRM) in the positive ion mode using the method of External standard. Mean coverage and relative standard deviations (DSR) of myclobutanil on the 0.01-0.20 mg / kg (-1) peak level amounted to 80.9% -90.7% and 5.54% -9, 29% and the limit of quantification (LQ) fraud 0.005 mg x kg (-1). The method with good, reproducible, high accuracy and low detection limit could meet the requirements of residue analysis of ginseng production. The half-lives of myclobutanil were 6.25 days to 9.94 days in root ginseng, stem, leaves and spray soil of 1,152 gx hm (-2). The endreste were among 0.060 1 mg x Kg (-1) in the root, 0.081 7 mg x kg (-1) in the boot, 0 to 0.102 0.006 2 mg x kg (-1) in the sheet and 0.037 6 mg x kg Of soil dosage range 576-1152 Gx hm (-2). It is recommended that myclobutanil MRLs can be assigned in dried ginseng at 0.10 mg kg (-1) x to be temporary, and the pre-harvest interval has been set at 35 days.
