Simazine - Mar, 02 2016

Common name: simazine
IUPAC name: 6-chloro-N2, N4-diethyl-1, 3, 5-triazine-2, 4-diamine
Chemical Abstracts name: 6-chloro-N, N'-diethyl-1, 3, 5-triazine-2, 4-diamine
CAS RN: [122-34-9]

PHYSICAL CHEMISTRY
Composition: Tech. grade is 97% pure. Mol. wt.: 201.7; M.f.: C7H12ClN5 Form: Colourless powder. M.p.: 225-227 ºC (decomp.) V.p.: 2.94x10-3 mPa (25 ºC) (OECD 104). KOW: logP = 2.1 (25 ºC, unionised). Henry: 5.6x10-5 Pa m3 mol-1 (calc.) S.g./density: 1.33 (22 °C). Solubility: In water 6.2 mg/l (pH 7, 20 ºC). In ethanol 570, acetone 1500, toluene 130, n-octanol 390, n-hexane 3.1 (all in mg/l, 25 ºC). Stability: Relatively stable in neutral, weakly acidic and weakly alkaline media. Rapidly hydrolysed by stronger acids and bases; DT50 (calc.) 8.8 d (pH 1), 96 d (pH 5), 3.7 d (pH 13) (20 °C). Decomposed by u.v. irradiation (c. 90% in 96 h). pKa: 1.62 (20 °C), v. weak base.

APPLICATIONS
Biochemistry: Photosynthetic electron transport inhibitor at the photosystem II receptor site. Maize tolerance of triazines is attributed to conjugation with glutathione.
Mode of action: Selective systemic herbicide, absorbed principally through the roots, but also through the foliage, with translocation acropetally in the xylem, accumulating in the apical meristems and leaves.
