Chemical Properties

green-brown to brown solution

Uses

Different sources of media describe the Uses of 693-04-9 differently. You can refer to the following data:
1. n-Butylmagnesium chloride is used in organic synthesis, pharmaceuticals, agrochemicals and dyestuffs.
2. Butylmagnesium chloride (BuMgCl) is a Grignard reagent that can be used:To prevent the formation of passivating surface films on Mg electrodes.For the synthesis of lithium tributylmagnesate complex (n-Bu3MgLi) by reacting with n-BuLi.

Check Digit Verification of cas no

The CAS Registry Mumber 693-04-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 693-04:
(5*6)+(4*9)+(3*3)+(2*0)+(1*4)=79
79 % 10 = 9
So 693-04-9 is a valid CAS Registry Number.

Disposable cartridge concept for the on-demand synthesis of turbo Grignards, Knochel–Hauser amides, and magnesium alkoxides

Magnesium organometallic reagents occupy a central position in organic synthesis. The freshness of these compounds is the key for achieving a high conversion and reproducible results. Common methods for the synthesis of Grignard reagents from metallic magnesium present safety issues and exhibit a batch-to-batch variability. Tubular reactors of solid reagents combined with solution-phase reagents enable the continuous-flow preparation of organomagnesium reagents. The use of stratified packed-bed columns of magnesium metal and lithium chloride for the synthesis of highly concentrated turbo Grignards is reported. A low-cost pod-style synthesizer prototype, which incorporates single-use prepacked perfluorinated cartridges and bags of reagents for the automated on-demand lab-scale synthesis of carbon, nitrogen, and oxygen turbo magnesium bases is presented. This concept will provide access to fresh organomagnesium reagents on a discovery scale and will do so independent from the operator’s experience in flow and/or organometallic chemistry.
