2-Methylbenzoxazole-5-sulphonic acid is an organic compound with the chemical formula C8H7NO4S. It is a derivative of benzoxazole, a heterocyclic aromatic ring system consisting of a benzene ring fused to an oxazole ring. The molecule features a methyl group attached to the benzene ring at the 2nd position, a sulphonic acid group at the 5th position of the benzoxazole ring, and a hydroxyl group at the 5th position as well. 2-methylbenzoxazole-5-sulphonic acid is known for its potential applications in the synthesis of dyes and pharmaceuticals, particularly as an intermediate in the production of certain colorants. It is also recognized for its reactivity and can be used in various chemical transformations due to the presence of the sulphonic acid group, which imparts acidic properties to the molecule.

6764-43-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6764-43-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,6 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6764-43:
(6*6)+(5*7)+(4*6)+(3*4)+(2*4)+(1*3)=118
118 % 10 = 8
So 6764-43-8 is a valid CAS Registry Number.

Asymmetric anthocyanin dye and application thereof

-

Paragraph 0060-0063; 0064-0067, (2018/09/13)

The invention provides a compound adopting an asymmetric anthocyanin dye structure. The compound has a general chemical structure formula (I). The compound has no fluorescence itself, but can produceintensive fluorescence signals when composited with RNA, has the intensity of the fluorescence signal directly proportional to the concentration of RNA and has high selectivity for RNA. Therefore, theconcentration of RNA in biological samples can be simply and quickly determined by use of the compound.
