4,5,6-triethoxy-7-nitrophthalide is a complex organic chemical compound with the molecular formula C14H17NO7. It is characterized by the presence of three ethoxy groups (-OCH2CH3) attached to the 4, 5, and 6 carbon atoms of the phthalide ring, and a nitro group (-NO2) at the 7 position. 4,5,6-triethoxy-7-nitrophthalide is a derivative of phthalide, which is a cyclic ester of phthalic acid. The presence of the nitro group imparts potential reactivity and may influence its chemical properties, such as its ability to act as an electrophile in certain reactions. The compound may be of interest in the field of organic synthesis, particularly for the development of pharmaceuticals or other specialty chemicals, due to its unique structure and potential reactivity.

4995-54-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4995-54-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4995-54:
(6*4)+(5*9)+(4*9)+(3*5)+(2*5)+(1*4)=134
134 % 10 = 4
So 4995-54-4 is a valid CAS Registry Number.

Process for preparation of phthalide derivatives

-

, (2008/06/13)

Disclosed herein is a process for preparing phthalide derivatives represented by the general formula (IV): STR1 wherein R1 to R7 are herein defined, comprising (i) reacting a nitrophthalide of the general formula (I) defined herein with an isoquinoline of the general formula (II) defined herein, and (ii) reducing the resultant phthalideisoquinoline of the general formula (III) defined herein. The process is characterized in (A) that the reaction defined in (i) is carried out in methanol, and/or (B) that the nitrophthalide of the general formula (I) is a nitrophthalide obtained by a reaction of a phthalide of the general formula (V) defined herein with copper nitrate or zinc nitrate.
