ТРИЭТАЗИН-ДЕЗЭТИЛ

Description

Triethazine-desethyl is a deethylation product of the herbicide triethazine, a compound of a series of chloro-1,3,5-triazines. According to suppliers of analytical standards, the systematic name is 6-chloro-2-N,2-N-diethyl-1,3,5-triazine-2,4-diamine; in the list of synonyms of the card, the option “2-amino-4-chloro-6-diethylamino-s-triazine” corresponds to it. A comparison with the original substance confirms the origin: triethazine has the formula C9H16ClN5, the metabolite has the formula C7H12ClN5, the difference is one ethyl fragment. The product is available as an analytical standard for the control of pesticide residues, typical purity 98% or higher, in the form of a white solid.

Basic Attributes

• CAS No.: 38902-68-0
• Chemical formula: C7H12ClN5
• Molecular Weight: 201.65668
• Exact weight: 201.07800
• DSSTox ID: DTXSID10192147
• HS code: 2933699090
• PSA specifications: 67.9
• XLogP3: 2.1
• Original active ingredient: triethazine, CAS 1912-26-1, C9H16ClN5

Physico-chemical properties

• Density: 1.3 g/cm³
• Boiling point: 388.1 °C at 760 mm Hg. Art.
• Flash point: 188.5 °C
• Refractive index: 1.606
• Solubility in water: none
• Steam pressure: 8.1 × 10⁻⁷ Pa at 20 °C

The combination of insolubility in water and a vapor pressure of the order of 10⁻⁷ Pa means that the substance is practically non-volatile and passes into the aqueous phase weakly: during sample preparation it is extracted with organic solvents or solid-phase extraction.

Scope of application

• analytical standard for the determination of pesticide residues in food products and environmental objects
• marker of triethazine deethylation in studies of herbicide behavior in soil, water and the body
• calibration substance for the validation of chromatographic and gas chromatography-mass spectrometric techniques

The compound has no actual use as a plant protection product: it is a metabolite, not an active substance.

Safety Information

• Hazard category: irritant
• Hazard class code: 40-50/53 - limited evidence of carcinogenicity; very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment
• Safety instructions: (2)-36/37-46-60-61
• Tags: Xn (harmful), N (dangerous for the environment)
• Harmonized phrases H and P, as well as transport classification are not given on the card - check with the batch passport

Storage and handling

Features of card storage: separate from food products, the container closes well. Label N and code 50/53 require that the substance not enter wastewater and water bodies. Work should be carried out in a fume hood, wearing gloves and safety glasses; When weighing, do not allow dust to form. Store in original packaging, protect from light and heat.

Note on card data

The list of synonyms for the original card contains mutually exclusive names. The formula C7H12ClN5 and the designation “triethazine-desethyl” correspond to the variant “2-amino-4-chloro-6-diethylamino-s-triazine” - the same structure as in the nomenclature of the standard suppliers. Names with the fragment “bis(dimethylamino)” describe another compound and do not apply to this CAS; they were transferred to the card by mistake. When ordering, refer to the CAS number and gross formula.
