稳定性/保质期:

分解:
When heated to decomposition it emits very toxic fumes of /hydrogen chloride, ammonia, & nitrogen oxides/.
HERBICIDAL ACTIVITY OF ESTERS, NITRILES, AMINES (&, OF COURSE, SALTS) APPEARS SIMILAR IF NOT IDENTICAL TO PARENT ACID. THIS IS APPARENTLY DUE TO PRESENCE OF HYDROLYTIC ENZYMES IN PLANTS & IN SOIL MICROORGANISMS THAT CONVERT THESE DERIVATIVES TO PARENT ACID.
Chlorophenoxy acid derivatives are metabolized via participation of the hepatic microsomal mixed-function oxidase system. Thus, administration of 2,4-D amine salt and its butyl ester ... to rats induced the enzyme system (aminopyrine demethylase ... and aniline hydroxylase) ... although the degree of induction was substantially lower than that from phenobarbital. Prolonged administration of 2,4-D amine salt (0.1 LD50) showed cumulative effects reflected by both clinical and biochemical changes. Stimulation of mixed-function oxidase system may be one of the methods for reducing toxicological effects of this type of compounds.

The dimethylamine salt of (14)C-ring-labeled 2,4-D was administered to Fisher 344 rats orally (1 and 0.4 mg/kg body weight) and dermally (10 mg/kg body weight). Absorption, distribution, and elimination were determined from (14)C-labeled 2,4-D in blood, tissues, and excreta. Most of the orally administered dose (94-96%) became systemically available within 6 hr. Following dermal administration 10% of the dose became systemically available over 72 hr. However, peak concentrations in blood and kidney were achieved within 30 min of dosing by either route. By 1.5 hr after dosing, 2,4-D concentrations in blood, muscle, liver, and kidneys had decreased in both the orally dosed and dermally dosed animals. Between 2 and 8 hr, the blood, muscle, liver, and kidney concentrations in dermally dosed animals maintained a plateau while urinary excretion increased, presumably due to continued absorption 2,4-D from the skin. The concentrations in orally dosed animals continued to decrease. Following 7 hr of dermal exposure, skin cleansing removed about 63% of the applied dose; about 17% of the applied dose remained at the site of dermal dosing. At 8 hr, 2,4-D concentrations in blood, muscle, liver, and kidneys of dermally dosed animals began to decrease, most likely a result of the removal of the reservoir on the skin. However, 2,4-D continued to be absorbed from skin site, resulting in a slower decline of the 2,4-D concentrations in these tissues over remainder of the 72 hr study period. In animals that had been orally dosed, the absorbed dose was almost completely excreted within 24 hr.
Plant roots absorb polar (salt) forms /of 2,4-D/ most readily. ... Following root absorption, it may move upward in the transpiration stream. Translocation is influenced by the growth status of the plant. Accumulation of the herbicide occurs principally at the meristematic regions of shoots and roots. /2,4-D salt/
Synthesis of Annulated γ-Carbolines by Palladium-Catalyzed Intramolecular Iminoannulation
摘要:
[GRAPHICS]A variety of N-substituted 2-bromo-1H-indole-3-carboxaldehydes incorporating an alkyne-containing tether on the indole nitrogen have been converted to the corresponding tert-butylimines, which have been subjected to palladium-catalyzed intramolecular iminoannulation, affording various annulated gamma-carbolines in excellent yields.
