84942-40-5 Usage
Uses
5′-Chloro-2′-hydroxy-3′-nitroacetophenone may be used for the synthesis of 6-chloro-8-nitro-4-oxo-4H-chromene-3-carbaldehyde.
Preparation
Preparation by reaction of nitric acid on 5-chloro-2- hydroxyacetophenone in acetic acid at r.t.
General Description
5′-Chloro-2′-hydroxy-3′-nitroacetophenone (5-chloro-3-nitro-2-hydroxyacetophenone) is a nitro derivative of ortho-hydroxy aryl ketone. Its crystal structure has been studied by X-ray diffraction. It forms complex with 2-aminobenzoic acid (anthranilic acid), in which the nitro group is turned by approximately 40°C.
Check Digit Verification of cas no
The CAS Registry Mumber 84942-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,4 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84942-40:
(7*8)+(6*4)+(5*9)+(4*4)+(3*2)+(2*4)+(1*0)=155
155 % 10 = 5
So 84942-40-5 is a valid CAS Registry Number.

A series of hydrazones Schiff bases compounds have been synthesized by reacting isonicotinoyl hydrazide with 2-hydroxy-5-chloro acetophenone, 2-hydroxy-5-methyl acetophenone, 2-hydroxy-5-carboxy acetophenone, 2,5-dihydroxy acetophenone, 2-hydroxy-5-chloro-4-methyl acetophenone, 2-hydroxy-5-chloro-3- nitro acetophenone, 2-hydroxy-5-methyl-3-nitro acetophenone and 2-hydroxy-5-bromo acetophenone. The Schiff bases have been evaluated for the antifungal and antibacterial activities.
