1,4-Phenylene diformate, also known as p-phenylene diformate or 1,4-benzenediformic acid diformate, is an organic compound with the chemical formula C10H8O4. It is a colorless, crystalline solid that is soluble in organic solvents. 1,4-phenylene diformate is formed by the reaction of 1,4-phenylene diisocyanate with formic acid, resulting in a diester with two ester groups attached to a benzene ring. 1,4-Phenylene diformate is used as an intermediate in the synthesis of various chemicals, including polyurethanes, polyamides, and other polymers. It is also employed in the production of specialty resins, adhesives, and coatings. Due to its reactivity and versatility, it plays a significant role in the chemical industry, particularly in the development of new materials with unique properties.

Check Digit Verification of cas no

The CAS Registry Mumber 33104-35-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,1,0 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 33104-35:
(7*3)+(6*3)+(5*1)+(4*0)+(3*4)+(2*3)+(1*5)=67
67 % 10 = 7
So 33104-35-7 is a valid CAS Registry Number.

A new simple method for the preparation of aryl formates from phenols

Hashmi, Imran Ali,Kantlehner, Willi,Ivanov, Ivo C.

, p. 478 - 480 (2008)

Aryl formates are prepared in a two step one-pot procedure from phenols. Firstly the formylating reagent triformamide (1b) is generated from sodium diformamide (2) and methane-sulfonyl chloride in situ, which reacts with phenols 4a-f to give aryl formates 5a-f in good yields. Triformamide, prepared in situ, transforms anisole in the presence of aluminum chloride to the N-(diarylmethyl)formamide 7.
