8001-88-5 Usage
Chemical Properties
The essential oil is obtained from the B. alba and B. pendula Roth.
Physical properties
The essential oil of B. alba L. is a viscous, yellow liquid with a balsamic odor. It is obtained
from buds by steam distillation in 3.5 to 8% yields. The oil solidifies at low temperature because of its paraffin content. The essential
oil of B. alba L. var. pubescens Ehrl., obtained from buds in 3.5% yields by steam distillation, has a specific gravity of 0.9779. The
essential oil of B. alba I. obtained from bark is recovered in 0.4 to 0.5% yields. The essential oil obtained from leaves is recovered
in 0.4 to 0.5% yields.
Occurrence
Found in the tar of the bark and wood of Betula pendula Roth (fam. Betulaceae).
Preparation
By steam-distillation of the tar obtained by dry distillation of the bark and the wood of Betula pendula Roth (fam. Betulaceae).
Safety Profile
A skin irritant. Moderatelyirritating to eyes and mucous membranes. A mild allergen.Combustible when exposed to heat or flame; can reactwith oxidizing materials.
Check Digit Verification of cas no
The CAS Registry Mumber 8001-88-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,0 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 8001-88:
(6*8)+(5*0)+(4*0)+(3*1)+(2*8)+(1*8)=75
75 % 10 = 5
So 8001-88-5 is a valid CAS Registry Number.
