Ethyl Tetrahydro-2-fuorate is a useful reactant for the synthesis of spiro/fused dihydrofurans and dihydropyrans.

Check Digit Verification of cas no

The CAS Registry Mumber 16874-34-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,7 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 16874-34:
133 % 10 = 3
So 16874-34-3 is a valid CAS Registry Number.

Preparation method of tetrahydrofuranacetic acid and ester compounds thereof


Paragraph 0020; 0029, (2021/05/12)

The invention provides a preparation method of tetrahydrofuranacetic acid and ester compounds thereof. The preparation method comprises the following steps: in a proper solvent, in a reducing atmosphere and under the action of a hydrogenation catalyst, carrying out a reduction reaction on furanacetic acid and ester compounds thereof under the conditions that a pressure is 0.1-10MPa and a temperature is 30-250 DEG C for 0.1-72 hours, separating out the catalyst, and distilling out the solvent to obtain the target products, namely tetrahydrofuranacetic acid and the ester compounds thereof. Under relatively mild and environment-friendly conditions, efficient conversion of bio-based furanacetic acid and esters thereof is achieved, industrial production of the reaction is facilitated, platform molecules can be converted into various important intermediates or terminal products through chemical catalysis upgrading to replace existing petrochemical products, dependence on fossil resources is reduced, and the application range of biomass is expanded.



Paragraph 0359; 0360; 0361; 0362; 0363; 0364, (2016/03/04)

What is proposed are specific tetrahydrofuran derivatives of the formula (I), fragrance and aroma substance mixtures comprising these tetrahydrofuran derivatives, their use in fragrance or aroma substance (mixture) and corresponding perfumed products.
