98-58-8 Usage

Uses

Different sources of media describe the Uses of 98-58-8 differently. You can refer to the following data:
1. 4-Bromobenzenesulfonyl chloride is used for identification of amines, and also in the synthesis and inhibition studies of substituted N-L-histidinylphenylsulfonyl hydrazide.
2. Identification of amines.
3. 4-Bromobenzenesulfonyl chloride is used as activating agent in the synthesis of oligodeoxyribo- and oligoribo- nucleotides in solution. It also used in the synthesis of 4-(N-allylsulfamoyl)phenylboronic acid and in protection of amines as 4-bromobenzenesulfonamides.

Purification Methods

Wash the sulfonyl chloride with cold water, dry and recrystallise it from pet ether, or from ethyl ether cooled in powdered Dry-Ice after the ether solution had been washed with 10% NaOH until colourless, then dry it with anhydrous Na2SO4. Alternatively dissolve it in CHCl3, wash it with H2O, dry (Na2SO4), evaporate and recrystallise it. [Huntress & Carten J Am Chem Soc 62 511 1940.] Test for the SO2Cl group by dissolving it in EtOH and boiling with NH4CNS whereby a yellow amorphous precipitate forms on cooling. [Beilstein 11 IV 162.]

Check Digit Verification of cas no

The CAS Registry Mumber 98-58-8 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, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 98-58:
(4*9)+(3*8)+(2*5)+(1*8)=78
78 % 10 = 8
So 98-58-8 is a valid CAS Registry Number.

NOVEL COMPOUND, PREPARATION METHOD THEREOF, AND USE THEREOF

-

Paragraph 530-534, (2021/07/24)

The present invention relates to a method for preparing a biomaterial having selectively functionalized tyrosine, a biomaterial having selectively functionalized tyrosine, and a pharmaceutical composition containing the same as an active ingredient. The method for preparing a biomaterial to which a compound represented by formula 2 is coupled, of the present invention, allows the compound represented by formula 2 to be selectively coupled, in a high yield in a biomaterial, to tyrosine, which is present on the surface of an aqueous solution such that the coupling thereof to amino acids other than tyrosine does not occur and, when only one tyrosine is present, heterogeneous mixtures are not present and the inherent activity of the biomaterial is maintained, and thus the compound can be effectively used as a pharmaceutical composition containing a biomaterial drug as an active ingredient. In addition, the method can selectively functionalize tyrosine, and thus can be effectively used for tyrosine functionalization in a biomaterial.

Copper-Catalyzed N-Directed Distal C(sp3)-H Sulfonylation and Thiolation with Sulfinate Salts

Chen, Guang-Le,He, Shi-Hui,Cheng, Liang,Liu, Feng

supporting information, p. 8338 - 8342 (2021/10/25)

We herein report a selective and catalytic C(sp3)-H functionalization approach to access amines bearing organo-sulfonyl and organo-thiol groups. This reaction proceeds through a cascade process of N-radical formation, alkyl radical formation via 1,5-HAT, and C-S bond formation, thereby offering a series of functionalized amines. This method could enable primary, secondary, and tertiary C(sp3)-H sulfonylation and thiolation and also exhibits good functional group tolerance.

Chromoselective Synthesis of Sulfonyl Chlorides and Sulfonamides with Potassium Poly(heptazine imide) Photocatalyst

Antonietti, Markus,Guldi, Dirk M.,Markushyna, Yevheniia,Savateev, Aleksandr,Schü?lbauer, Christoph M.,Ullrich, Tobias

supporting information, p. 20543 - 20550 (2021/08/12)

Among external stimuli used to promote a chemical reaction, photocatalysis possesses a unique one—light. Photons are traceless reagents that provide an exclusive opportunity to alter chemoselectivity of the photocatalytic reaction varying the color of incident light. This strategy may be implemented by using a sensitizer capable to activate a specific reaction pathway depending on the excitation light. Herein, we use potassium poly(heptazine imide) (K-PHI), a type of carbon nitride, to generate selectively three different products from S-arylthioacetates simply varying the excitation light and otherwise identical conditions. Namely, arylchlorides are produced under UV/purple, sulfonyl chlorides with blue/white, and diaryldisulfides at green to red light. A combination of the negatively charged polyanion, highly positive potential of the valence band, presence of intraband states, ability to sensitize singlet oxygen, and multi-electron transfer is shown to enable this chromoselective conversion of thioacetates.
