Used in Dye Industry:
3-Aminobenzotrifluoride is used as a chemical intermediate in the production of dyes. Its unique chemical properties make it suitable for use in the synthesis of various types of dyes, contributing to the color and stability of the final product.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
3-Aminobenzotrifluoride is a halogenated amine derivative. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
Health Hazard
Contact may cause burns to skin and eyes. May be poisonous if inhaled, swallowed or absorbed through the skin.
Fire Hazard
3-Aminobenzotrifluoride may burn but does not ignite readily. Cylinder may explode in heat of fire. When heated to decomposition, 3-Aminobenzotrifluoride emits very toxic fumes of fluorides and nitrogen oxides.
Safety Profile
Poison by inhalation, ingestion, and intraperitoneal routes. May be moderately toxic by other routes. See also AMINES and FLUORIDES. When heated to decomposition it emits very toxic fumes of Fand NOx,.
Potential Exposure
This material is used as a chemical
intermediate for herbicides, antihypertensives, and diuretics.
Shipping
UN29483-Trifluoromethylaniline, Hazard Class:
6.1; Labels: 6.1—Poisonous materials.
Incompatibilities
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions.
Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides. Light and air sensitive.
Check Digit Verification of cas no
The CAS Registry Mumber 98-16-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 98-16:
(4*9)+(3*8)+(2*1)+(1*6)=68
68 % 10 = 8
So 98-16-8 is a valid CAS Registry Number.

Paragraph 0006; 0025-0028, (2021/07/31)
The invention relates to a hydroboration reduction reaction of aromatic nitro compounds without transition metal catalysis. According to the method, triethyl boron and potassium tert-butoxide are used as catalysts for the first time, and an aromatic nitro compound and pinacol borane which is low in price and easy to obtain can be conveniently catalyzed to be subjected to a hydroboration reduction reaction under mild conditions to prepare aromatic amine products. Compared with a traditional method, the method generally has the advantages that the catalyst is cheap and easy to obtain, operation is convenient, and reaction is safe. The selective hydroboration reduction reaction of the non-transition metal reagent catalyzed aromatic nitro compound and pinacol borane is realized for the first time, and a practical new reaction strategy is provided for laboratory preparation or industrial production of aromatic amine products.

Starting from nitroarenes, under hydrosilylation conditions, using a well-defined N-heterocyclic carbene iron(0) catalyst, (IMes)Fe(CO)4, the corresponding aniline derivatives were produced in 61–92% isolated yields. More impressively, a selective synthesis of cyclic amines such as pyrrolidines, piperidines and azepanes were conducted from levulinic acid, 1,5- and 1,6-keto acids, respectively. The sequential procedure proceeded under both visible light irradiation and thermal conditions with 20 examples in isolated yields up to 69%. (Figure presented.).

supporting information, p. 9419 - 9424 (2021/11/30)
We report a new set of reactions based on the unlocking of amides through simple treatment with allyl bromide, creating a common platform for accessing a diverse range of nitrogen-containing functional groups such as primary amides, sulfonamides, primary amines, N-acyl compounds (esters, thioesters, amides), and N-sulfonyl esters. The method has potential industrial applicability, as demonstrated through gram-scale syntheses in batch and in a continuous flow system.
