65165-91-5 Usage
Description
Folic acid, also known as vitamin B9, is a water-soluble vitamin that plays a crucial role in the synthesis of DNA, DNA repair, and DNA methylation. It also serves as a cofactor in various biological reactions involving folate.
Uses
Used in Pharmaceutical Industry:
Folic acid is used as a dietary supplement for preventing and treating folic acid deficiency, which can lead to various health issues such as anemia, neural tube defects in pregnant women, and other complications.
Used in Food Fortification:
Folic acid is used as a fortifying agent in various food products, such as cereals, bread, and pasta, to ensure adequate intake of this essential vitamin and to promote overall health.
Used in Cosmetic Industry:
Folic acid is used as a skin care ingredient in cosmetic products, as it helps promote skin health, improve skin elasticity, and reduce the appearance of fine lines and wrinkles.
Used in Research Applications:
Folic acid is used as a research tool in various scientific studies, particularly in the fields of genetics, molecular biology, and cancer research, due to its role in DNA synthesis and repair.
Check Digit Verification of cas no
The CAS Registry Mumber 65165-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,1,6 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 65165-91:
(7*6)+(6*5)+(5*1)+(4*6)+(3*5)+(2*9)+(1*1)=135
135 % 10 = 5
So 65165-91-5 is a valid CAS Registry Number.

Efficient syntheses of pyrofolic acid and pteroyl azide, reagents for the production of carboxyl-differentiated derivatives of folic acid
Luo, Jin,Smith, Michael D.,Lantrip, Douglas A.,Wang, Susan,Fuchs
, p. 10004 - 10013 (2007/10/03)
Reaction of folic acid (1) with excess trifluoroacetic anhydride provides access to both the previously unknown N10-(trifluoroacetyl)pyrrofolic acid (8) and pyrofolic acid (9). Reaction of either of these materials with hydrazine selectively affords pteroyl hydrazide (13), which may be oxidized to pteroyl azide (27) on a large scale (62% overall from I without the need for chromatography). Treatment of 27 with differentially protected glutamates provides a convenient and high-yielding synthesis of differentially protected, optically pure folates.
