19900-65-3 Usage

Uses

4,4'-methylenebis(2-ethylbenzenamine) be used for preparation polyimide and epoxy resin material.

Check Digit Verification of cas no

The CAS Registry Mumber 19900-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,0 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19900-65:
(7*1)+(6*9)+(5*9)+(4*0)+(3*0)+(2*6)+(1*5)=123
123 % 10 = 3
So 19900-65-3 is a valid CAS Registry Number.

, (2008/06/13)

The present invention provides a salt represented by the formula (I): wherein P1, P2 and P3 each independently represent a C1-C30 alkyl group which may be substituted with at least one selected from a hydroxyl group, a C3-C12 cyclic hydrocarbon group and a C1-C12 alkoxy group, or a C3-C30 cyclic hydrocarbon group which may be substituted with at least one selected from a hydroxyl group and a C1-C12 alkoxy group, provided that all of P1, P2 and P3 are not simultaneously phenyl groups which may be substituted, Q1 and Q2 each independently represent a fluorine atom or a C1-C6 perfluoroalkyl group, and R represents a group represented by the formula: wherein A1 represents —OH or —Y1—OH, n represents an integer of 1 to 9, and Y1 represents a divalent C1-C6 saturated aliphatic hydrocarbon group; a group represented by the formula: wherein ring X1 represents a C3-C30 monocyclic or polycyclic hydrocarbon group in which one —CH2— group is substituted with —CO—, and at least one hydrogen atom in the monocyclic or polycyclic hydrocarbon group may be substituted with a C1-C6 alkyl group, a C1-C6 alkoxy group, a C1-C4 perfluoroalkyl group, a C1-C6 hydroxyalkyl group, a hydroxyl group or a cyano group; a group represented by the formula: wherein ring X2 represents a C3-C30 monocyclic or polycyclic hydrocarbon group in which a hydrogen atom of one —CH2— group is substituted with a hydroxyl group, and at least one hydrogen atom in the monocyclic or polycyclic hydrocarbon group may be substituted with a C1-C6 alkyl group, a C1-C6 alkoxy group, a C1-C4 perfluoroalkyl group, a C1-C6 hydroxyalkyl group, a hydroxyl group or a cyano group; a group represented by the formula: wherein ring X3 represents a C3-C30 monocyclic or polycyclic hydrocarbon group in which one —CH2— group is substituted with —COO—, and at least one hydrogen atom in the monocyclic or polycyclic hydrocarbon group may be substituted with a C1-C6 alkyl group, a C1-C6 alkoxy group, a C1-C4 perfluoroalkyl group, a C1-C6 hydroxyalkyl group, a hydroxyl group or a cyano group, and m represents an integer of 0 to 12; or a group represented by the formula: wherein ring X4 represents a C6-C30 polycyclic hydrocarbon group having tricycle or more, and at least one hydrogen atom in the polycyclic hydrocarbon group may be substituted with a C1-C6 alkyl group, a C1-C6 alkoxy group, a C1-C4 perfluoroalkyl group, a C1-C6 hydroxyalkyl group or a cyano group, and l represents an integer of 1 to 12. The present invention further provides a chemically amplified resist composition comprising the salt represented by the above-mentioned formula (I).
