6921-28-4 Usage
General Description
Dipropargylamine is a chemical compound that belongs to the class of organic compounds known as propargyl-type 1,2-dipolar organic compounds. It is primarily characterized by its reactivity and is utilized in a variety of industrial applications including the production of polymers and as a corrosion inhibitor. Its chemical formula is C6H9N, and it is a colorless to slightly yellow liquid with a powerful unpleasant odor. The chemical is flammable, can be harmful if inhaled or swallowed, and may cause skin and eye irritation. It is essential to use proper handling and storage guidelines layed out by safety regulations to avoid incidents.
Check Digit Verification of cas no
The CAS Registry Mumber 6921-28-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,2 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6921-28:
(6*6)+(5*9)+(4*2)+(3*1)+(2*2)+(1*8)=104
104 % 10 = 4
So 6921-28-4 is a valid CAS Registry Number.

Substituted Propargylamines—Acid Corrosion Inhibitors for Steel in Petroleum Industry
Avdeev, Ya. G.,Dzhafarova, U. Sh.,Shatirova, M. I.
, p. 1088 - 1096 (2021/11/30)
Secondary and tertiary amines of the acetylene series of various structures (14 compounds) were synthesized based on propargylamine. The possibility of a significant inhibition with these substances of low-carbon steel corrosion in hot solutions of hydrochloric acid was established. The protective effect of acetylenic amines rose with an increase in their content in an aggressive environment and with an increase in its temperature. The maximum protection effect is provided by tertiary amines containing 2,3-epoxypropyl or 2,3-epithiopropyl as a substituent. The presence of chemically active epoxy and epithio groups in the structure of these acetylenic compounds promoted the stimulation of their polymerization on the steel surface through the opening of C≡C bonds, leading to the rapid formation of a protective polymer film on it.
