557-17-5 Usage

General Description

1-Methoxypropane, also known as methyl propyl ether, is a colorless liquid with a sweet odor. It is a solvent that is used in various industrial applications, including as a cleaner and degreaser in the electronics and automotive industries. It is also used as a fuel additive and as a component in some paint and coatings. 1-Methoxypropane is flammable and should be handled with care. It has low acute toxicity but can cause irritation to the skin, eyes, and respiratory system upon prolonged exposure. It is important to use proper safety measures and protective equipment when handling this chemical.

Check Digit Verification of cas no

The CAS Registry Mumber 557-17-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 557-17:
(5*5)+(4*5)+(3*7)+(2*1)+(1*7)=75
75 % 10 = 5
So 557-17-5 is a valid CAS Registry Number.

New perspectives for parahydrogen-induced polarization in liquid phase heterogeneous hydrogenation: An aqueous phase and ALTADENA study

Controlling the Lewis Acidity and Polymerizing Effectively Prevent Frustrated Lewis Pairs from Deactivation in the Hydrogenation of Terminal Alkynes

Geng, Jiao,Hu, Xingbang,Liu, Qiang,Wu, Youting,Yang, Liu,Yao, Chenfei

, p. 3685 - 3690 (2021/05/31)

Two strategies were reported to prevent the deactivation of Frustrated Lewis pairs (FLPs) in the hydrogenation of terminal alkynes: reducing the Lewis acidity and polymerizing the Lewis acid. A polymeric Lewis acid (P-BPh3) with high stability was designed and synthesized. Excellent conversion (up to 99%) and selectivity can be achieved in the hydrogenation of terminal alkynes catalyzed by P-BPh3. This catalytic system works quite well for different substrates. In addition, the P-BPh3 can be easily recycled.

Iron-Catalyzed Ring-Closing C?O/C?O Metathesis of Aliphatic Ethers

Biberger, Tobias,Makai, Szabolcs,Lian, Zhong,Morandi, Bill

supporting information, p. 6940 - 6944 (2018/05/14)

Among all metathesis reactions known to date in organic chemistry, the metathesis of multiple bonds such as alkenes and alkynes has evolved into one of the most powerful methods to construct molecular complexity. In contrast, metathesis reactions involving single bonds are scarce and far less developed, particularly in the context of synthetically valuable ring-closing reactions. Herein, we report an iron-catalyzed ring-closing metathesis of aliphatic ethers for the synthesis of substituted tetrahydropyrans and tetrahydrofurans, as well as morpholines and polycyclic ethers. This transformation is enabled by a simple iron catalyst and likely proceeds via cyclic oxonium intermediates.
