Buying (R)-(+)-2-methyl-2-propanesulfinamide (CAS 196929-78-9) for asymmetric synthesis means the chiral purity matters as much as the chemical purity. This guide explains what to specify, what the COA must show, and how to store the reagent. 1.

Ellman’s sulfinamide (CAS 196929-78-9) is the reagent of choice when a synthesis needs a single enantiomer of a chiral amine. This guide walks through the practical route – condensation, diastereoselective addition, cleavage – and the points that decide success at scale. 1. The Three-Step Logic Step Reaction Key control 1.

(R)-(+)-2-Methyl-2-propanesulfinamide (CAS 196929-78-9, C4H11NOS, MW 121.20) – commonly known as Ellman’s sulfinamide – is one of the most widely used chiral auxiliaries in asymmetric synthesis. It converts aldehydes and ketones into N-sulfinyl imines that undergo highly diastereoselective addition, giving enantiopure chiral amines after cleavage. This guide covers its chemistry, use and specifications. 1. What Is
