885519-56-2 Usage
General Description
"1H-Indazole,6-chloro-4-iodo-" is a specific type of chemical compound that belongs to the indazole class, characterized by a bicyclic structure which includes two nitrogen atoms in the five-membered ring. The notation "1H" indicates the presence of a hydrogen atom, while the "6-chloro-4-iodo" denomination suggests that a chlorine atom is attached at position 6 and an iodine atom at position 4 in the indazole ring structure. It's often used in the field of pharmaceutical research and in the synthesis of various organic compounds. The exact properties of this chemical can drastically vary depending on its specific formulation and it is involved in sophisticated chemical reactions requiring experienced handling.
Check Digit Verification of cas no
The CAS Registry Mumber 885519-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,5,5,1 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 885519-56:
(8*8)+(7*8)+(6*5)+(5*5)+(4*1)+(3*9)+(2*5)+(1*6)=222
222 % 10 = 2
So 885519-56-2 is a valid CAS Registry Number.

Application of C-H Functionalization in the Development of a Concise and Convergent Route to the Phosphatidylinositol-3-kinase Delta Inhibitor Nemiralisib

This paper describes the development of an improved and scalable method for the manufacture of nemiralisib, a phosphatidylinositol-3-kinase delta inhibitor. Incorporation of three consecutive catalytic reactions, including a palladium-catalyzed C-H functionalization and an iridium-catalyzed borylation, significantly simplified and shortened the synthetic sequence. The revised route was successfully implemented in a pilot plant on a multikilogram scale to deliver >100 kg of product.
