Description
TITAN YELLOW, also known as Thiazole Yellow G, is a pH-sensitive chromoionophore and a triazene dye. It is characterized by its orange-yellow crystals or powder form and is soluble in water and ethanol, displaying a lemon yellow color. The dye solution changes color when mixed with strong acids or bases, resulting in gold orange or orange precipitation, respectively.
Uses
Used in Textile Industry:
TITAN YELLOW is used as a dye for cellulose fibers, such as cotton, viscose rayon, and natural silk. It is favored for its ability to produce vibrant and long-lasting colors on these materials.
Used in Biological Stains:
TITAN YELLOW is used as a biological stain due to its ability to bind and highlight specific structures within cells and tissues, making it easier to observe and analyze them under a microscope.
Used in Analytical Chemistry:
TITAN YELLOW is used as an analytical reagent, most often for the determination of magnesium (Mg) in various samples.
Used as a pH Indicator:
TITAN YELLOW functions as a pH indicator, with its color changing from yellow (pH 11.0) to red (pH 13.0), making it useful for monitoring pH levels in various applications.
Used in Microscopy:
TITAN YELLOW is used as a fluorescent dye for microscopy, allowing for the visualization of specific structures or components within samples.
Used in Other Industries:
TITAN YELLOW is also used in the leather, paper, and shading industries, where its coloring properties are beneficial for various applications.
Standard:
The standard for TITAN YELLOW includes ratings for acid resistance, alkali resistance, light fastness, soaping, water fading, and stain fading. According to the ISO and AATCC standards, TITAN YELLOW has the following ratings:
Acid Resistance: ISO 2, AATCC 1
Alkali Resistance: ISO 1, AATCC 1
Light Fastness: ISO 1, AATCC 1
Soaping: ISO 2-3, AATCC 3
Water Fading: Not specified
Stain Fading: Not specified
These ratings indicate the dye's performance and stability under various conditions, making it a versatile choice for different applications.
Preparation
2-(4-Aminophenyl)-6-methylbenzo[d]thiazole-7-sulfonic acid diazo, and the 2-(4-Aminophenyl)-6-methylbenzo[d]thiazole-7-sulfonic acid?coupling. In some closely related to the grade of the dyes, as one or two to a generation of 2-(4-Aminophenyl)-6-methylbenzo[d]thiazole-7-sulfonic acid?C.I.Direct Yellow 59 (C.I. 49000) instead. For example, Oxydiamine Yellow TZM structure is the 2-(4-Aminophenyl)-6-methylbenzo[d]thiazole-7-sulfonic acid?and C.I.Direct Yellow 59?matches generated.
Composition
The bark contains from 24 to 42% of tannin and also contains gallic acid

Check Digit Verification of cas no
The CAS Registry Mumber 1829-00-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,2 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1829-00:
(6*1)+(5*8)+(4*2)+(3*9)+(2*0)+(1*0)=81
81 % 10 = 1
So 1829-00-1 is a valid CAS Registry Number.
