104356-27-6 Usage
General Description
Ethyl 4-hydroxy-2-nitrobenzoate is a chemical compound with the molecular formula C9H9NO5. It is derived from the reaction of 4-hydroxy-2-nitrobenzoic acid with ethanol. Ethyl 4-hydroxy-2-nitrobenzoate is commonly used in the pharmaceutical industry as an intermediate in the synthesis of various drugs and active pharmaceutical ingredients. It possesses antioxidant properties and is also used in the production of cosmetic and personal care products. Ethyl 4-hydroxy-2-nitrobenzoate is a yellow crystalline powder with a melting point of 107-111°C and is considered to be stable under normal conditions of use and storage. However, it is recommended to handle this compound with care and follow proper safety precautions due to its potential hazards if mishandled.
Check Digit Verification of cas no
The CAS Registry Mumber 104356-27-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,3,5 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 104356-27:
(8*1)+(7*0)+(6*4)+(5*3)+(4*5)+(3*6)+(2*2)+(1*7)=96
96 % 10 = 6
So 104356-27-6 is a valid CAS Registry Number.

Optical element and compounds used in its manufacture

, (2008/06/13)
An optical frequency conversion element has a wave-guiding layer which consists of a χ(2) -active ferroelectric liquid crystal. The monomeric or polymeric liquid crystal material has a periodic structure which permits the so-called quasi phase matching of a guided laser beam. The period length of the structure is equal to twice the coherence length lc =?/Δβ of the material, whereby Δβ=βo (2ω)-2βo (ω), with ω=angular frequency of the fundamental wave, 0=zero-order mode and β=propagation constant of the mode.
