21639-41-8 Usage

General Description

2-Formylbenzenesulfonyl chloride, also known as benzenesulfonyl chloride, is a chemical compound with the molecular formula C7H5ClO2S. It is a reactive and versatile reagent used in organic synthesis, particularly in the formation of amides and sulfonamides. 2-FORMYLBENZENESULFONYL CHLORIDE is a useful building block for creating pharmaceuticals, agrochemicals, and materials. It is also used in the production of dyes, pigments, and polymers. 2-Formylbenzenesulfonyl chloride is a highly toxic and corrosive chemical, so proper safety precautions and handling procedures must be followed when working with it.

Check Digit Verification of cas no

The CAS Registry Mumber 21639-41-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,3 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21639-41:
(7*2)+(6*1)+(5*6)+(4*3)+(3*9)+(2*4)+(1*1)=98
98 % 10 = 8
So 21639-41-8 is a valid CAS Registry Number.

An Exploration of Chemical Properties Required for Cooperative Stabilization of the 14-3-3 Interaction with NF-κB—Utilizing a Reversible Covalent Tethering Approach

Protein-protein modulation has emerged as a proven approach to drug discovery. While significant progress has been gained in developing protein-protein interaction (PPI) inhibitors, the orthogonal approach of PPI stabilization lacks established methodologies for drug design. Here, we report the systematic ″bottom-up″ development of a reversible covalent PPI stabilizer. An imine bond was employed to anchor the stabilizer at the interface of the 14-3-3/p65 complex, leading to a molecular glue that elicited an 81-fold increase in complex stabilization. Utilizing protein crystallography and biophysical assays, we deconvoluted how chemical properties of a stabilizer translate to structural changes in the ternary 14-3-3/p65/molecular glue complex. Furthermore, we explore how this leads to high cooperativity and increased stability of the complex.

Synthesis of 4-unsubstituted 2H-1,2,3-benzothiadiazine 1,1-dioxides via ortho lithiation of protected benzaldehyde derivatives

, p. 286 - 293 (2014/01/06)

Variously substituted 2-phenyl-1,3-dioxolanes and 2-(2-bromophenyl)-1,3- dioxolanes, prepared from the corresponding benzaldehydes, were lithiated ortho to the acetal group. Reaction of the lithio derivatives with sulfur dioxide led to the lithium sulfinate salts, which gave, upon oxidative chlorination with sulfuryl chloride, the corresponding benzenesulfonyl chlorides. Then, depending on the aromatic substitution pattern of the molecule, several protocols were elaborated for the functional group transformations leading to the target compounds. Ring closure was performed with hydrazine hydrate or acetylhydrazine, in the latter case with one-pot removal of the acetyl group. The 4-unsubstituted 2H-1,2,3-benzothiadiazine 1,1-dioxides thus obtained are potential drug candidates based on their structural similarity to biologically active phthalazinones.
