Usage

Description

DISPERSE YELLOW 2 is a synthetic dye characterized by its brilliant yellow color. It is commonly used in the textile industry for coloring various types of fibers, including polyester, acetate, and plastic.

Uses

Used in Textile Industry:
DISPERSE YELLOW 2 is used as a coloring agent for polyester, acetate, and plastic fibers due to its brilliant yellow color and ability to provide good colorfastness properties.
DISPERSE YELLOW 2 is used as a coloring agent for polyester fibers for their bright yellow color and good light fastness, perspiration fastness, and washing fastness. The AATCC rating for light fastness is 5, perspiration fastness is 2, and washing fastness is 1.
DISPERSE YELLOW 2 is also used as a coloring agent for acetate fibers, providing good colorfastness properties such as light fastness, perspiration fastness, and washing fastness. The AATCC rating for light fastness is 5, perspiration fastness is 2, and washing fastness is 1.
In addition, DISPERSE YELLOW 2 is used as a coloring agent for plastic materials, offering good colorfastness properties and resistance to fading and staining.

Fluorescent nitric oxide donor for the detection and killing of: Pseudomonas aeruginosa

The epidemic of multidrug-resistant bacteria calls for the improvement of both detection methods for bacterial infections and methods of treatment. Nitric oxide is a known potent antibacterial agent, but due to its gaseous and highly reactive nature, it is difficult to incorporate into a stable antibacterial compound. In this paper, we synthesize a nitric oxide donor attached to a fluorescent compound, creating a material that can both detect and kill the deadly multi-drug resistant bacteria strain Pseudomonas aeruginosa. Detection occurs through a bacterial enzyme-activated color change, showing a clear and obvious change from blue to yellow under UV light. The synthesized compound spontaneously releases 853 μmol of nitric oxide/g from a 10 mM initial concentration. Antibacterial efficacy studies after exposing Pseudomonas aeruginosa to a 10 mM dose of the synthesized compound show a 55-75% reduction in bacteria after 24 hours. This work is the first instance of a small molecule dual-function material that can both detect and kill bacteria.

Nitration of the Acetanilide-type Compounds

Some aromatic compounds containing the imino group (NH) were nitrated in acetic acid or anhydride, and the ortho/para ratios were measured.N-Methyl derivatives of the aforementioned compounds are much less reactive when nitrated under comparable conditions and give significantly lower o/p ratios.These results along with the literature data support the hypothesis that the acetanilide-type compounds are nitrated via N-nitro intermediates.
