883-21-6 Usage
Uses
1-Methoxy-2-naphthoic acid may be used in the synthesis of 2-(1-methoxy-2-naphthyl)-4,4-dimethyl-2-oxazoline. It may also be used in the synthesis of the following compounds:1-sec-butyl-2-naphthoic acid1-tert-butyl-2-naphthoic acid1-ethyl-2-naphthoic acid1-vinyl-2-naphthoic acid 1-phenyl-2-naphthoic acid1-(2,5-dimethylphenyl)-2-naphthoic acid2′-methoxy-[1,1′-binaphthalene]-2-carboxylic acid
General Description
1-Methoxy-2-naphthoic acid can be prepared from 1-methoxynaphthalene. 1-Methoxy-2-naphthoic acid can also be synthesized by reacting potassium tert-butoxide with 1-methoxynaphthalene and butyllithium in the presence of cyclohexane and tetrahydrofuran. It undergoes reduction in the presence of lithium to afford tetrahydronaphthoic acid.
Check Digit Verification of cas no
The CAS Registry Mumber 883-21-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,8 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 883-21:
(5*8)+(4*8)+(3*3)+(2*2)+(1*1)=86
86 % 10 = 6
So 883-21-6 is a valid CAS Registry Number.

Hydrogen peroxide oxidation of naphthalene derivatives catalyzed by poly (bis-1,2-diphenylene) diselenide
Giurg,Syper,Mlochowski
, p. 231 - 238 (2007/10/03)
Oxidation of 1- and 2-substituted naphthalenes (1) with 30% hydrogen peroxide in the presence of poly(bis-1,2-diphenylene) diselenide (PPDS) has been investigated. Depending on the substrate used trans-2-carboxycinnamic acid (2), and its isomer, (1-oxo-1,3-dihydroisobenzofuran-1-yl)acetic acid (3) or 2-naphthoic acid (4b) was a major product. Oxidation of hydroxynaphthalenes 1b and 1c is a convenient way to obtain trans-2-carboxy cinnamic acid (2) in almost quantitative yield. The mechanism of the reaction is postulated.
