12540-13-5 Usage
Description
Copper(2+) ethynediide, also known as cupric acetylide, is a brownish-black powder that is insoluble in water. It is a brown-black solid that is highly sensitive to impact or friction, making it a potential candidate for use as a detonator. However, its applications are limited due to this high sensitivity and its tendency to form and build up upon prolonged contact of copper metal with organic vapors.
Uses
Used in Explosive Industry:
Copper(2+) ethynediide is used as a detonator for its high sensitivity to impact or friction. Its application in this industry is due to its ability to initiate explosive reactions, making it a valuable component in the manufacturing of explosives.
However,
Preparation
Copper(II) acetylide may be prepared by passing alkyl acetylene vapors over aqueous solution of ammoniacal copper salt.
Hazard
Copper(II) acetylide is highly sensitive to impact, friction or heat. Mild impact or heating can cause a violent explosion. In the dry state it is flammable and is more sensitive to impact or friction than copper(I) acetylide.
Fire Hazard
Cupric acetylide is much more sensitive to
impact and friction than the cuprous salt.
Friction heating or mild impact can result in
violent explosion. In dry state, its sensitivity
is much greater to impact and is flammable.
Safety Profile
Confirmed carcinogen.
Cases of berylliosis have been reported from
exposure to so-called low berylhum alloys.
Human systemic effects by inhalation:
dyspnea, fibrosing alveolitis, weight loss, or
decreased weight gain. See also

COPPER COMPOUNDS. When heated to
decomposition it emits very toxic fumes of
BeO.
Check Digit Verification of cas no
The CAS Registry Mumber 12540-13-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,5,4 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 12540-13:
(7*1)+(6*2)+(5*5)+(4*4)+(3*0)+(2*1)+(1*3)=65
65 % 10 = 5
So 12540-13-5 is a valid CAS Registry Number.
