8021-29-2 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 8021-29-2 differently. You can refer to the following data:
1. Siberian fir needle oil is obtained by steam distillation of needles and twigs of Abies sibirica Ledeb., the Siberian silver fir. It is an almost
colorless or pale yellow liquid with a characteristic fir odor.
d2020 0.895–0.912; n20D 1.468–1.473; α20D ?40 ° to ?25 °; solubility: 1 vol in
≤10 vol of 90% ethanol.The main constituents are bornyl acetate (20–35%) and the monoterpene hydrocarbons α-pinene (10–22%) and camphene (15–26%). The main producer of Siberian fir needle oil is Russia, with a quantity of ~50 t/yr.
2. Abies sibirica oil is obtained by steam distillation of the needles and twigs of Siberian fr The oil has a fragrant pine- like odor and pungent taste.
Physical properties
The oil is an almost colorless to very slightly yellow liquid.
Uses
Odorant in perfumery, flavoring agent.
Definition
An essential oil obtained by the steam distillation of needles and twigs of several varieties of coniferous trees (Abies) native to both Canada and Siberia.
Essential oil composition
Main constituents of silver fur needles and twig oil include l-α-pinene, l-limonene, l-bornyl acetate, lauric
and decyclic aldehydes, and probably a sesquiterpene.
Safety Profile
Mildly toxic by
ingestion. A human and experimental skin
irritant. When heated to decomposition it
emits acrid smoke and irritating fumes.
Check Digit Verification of cas no
The CAS Registry Mumber 8021-29-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,2 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 8021-29:
(6*8)+(5*0)+(4*2)+(3*1)+(2*2)+(1*9)=72
72 % 10 = 2
So 8021-29-2 is a valid CAS Registry Number.
