4702-90-3 Usage
Description
Solvent Yellow 93 is a yellow-green light yellow powder that is insoluble in water but soluble in various organic solvents such as ethanol, chloroform, and acetone. It is characterized by its stable light fastness and heat resistance up to 300°C, as well as its compatibility with sodium carbonate and hydrochloric acid solutions.
Uses
Used in Textile Industry:
Solvent Yellow 93 is used as a coloring agent for polyester protoplasmic coloring, providing a vibrant and stable yellow hue to the fabric.
Used in Plastics Industry:
Solvent Yellow 93 is used as a coloring agent in the manufacture of polyester masterbatch, which is a concentrated mixture of colorants and additives that can be added to plastics during the production process to achieve the desired color.
Used in Other Industries:
Solvent Yellow 93 may also be used in other industries where yellow coloring is required, such as in the production of inks, coatings, and other colored products. Its solubility in organic solvents and stability under various conditions make it a versatile choice for a range of applications.

Check Digit Verification of cas no
The CAS Registry Mumber 4702-90-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4702-90:
(6*4)+(5*7)+(4*0)+(3*2)+(2*9)+(1*0)=83
83 % 10 = 3
So 4702-90-3 is a valid CAS Registry Number.

6-Substituted 5-formyl uracils undergo an interesting reaction with 1-phenyl-3-methyl-5-pyrazolone in the presence of base catalyst to afford deformylated uracils and 4,4¢-methylidenebis(1-phenyl-3-methyl-5- pyrazolone) in excellent yields. Georg Thieme V

Condensation of 5-chloro-4-formyl-3-methyl-1-phenylpyrazole (1) with malononitrile in the presence of piperidine or ammonium acetate affords the corresponding pyrazole derivatives (2-4). Base-catalyzed cyclocondensation of 1 with hippuric acid or ethyl glycinate hydrochloride gives the oxazolone 6 and 5-amino-3-methyl-6-oxo-1-phenyl-1,6-dihydropyrano[2,3-c]pyrazole (7) respectively. Treatment of 1 with ethyl cyanoacetate in basic medium produce ethyl α-cyano-β-(5-chloro-3-methyl-1-phenylpyrazol-4-yl)acrylate (8) which reacts with nitrogen nucleophiles to give compounds 9-12. Transesterification and/or hydrolysis of ester group has been observed on treatment of 8 with methyl alcohol in basic medium leading to the formation of acrylate derivatives (13-15). Compound 8 on treatment with ethyl acetoacetate or cyclohexanone undergoes condensation with subsequent cyclization and/or dearylation to give the adducts 16 and 17 respectively. Structures of all the products have been established by elemental analysis, IR, PMR and mass spectral data.
