2-oxo-propane-1,1,1-tricarboxylic acid trimethyl ester, also known as methyl citrate, is a naturally occurring organic compound derived from citric acid. It is a colorless, viscous liquid with a molecular formula of C7H10O7 and a molecular weight of 210.15 g/mol. Methyl citrate is widely used as a food additive, serving as a flavor enhancer, preservative, and emulsifier. It is also employed in the pharmaceutical and cosmetic industries as a solvent and carrier. The compound is produced by esterifying citric acid with methanol, resulting in a mixture of three isomers: 1,2,3-trimethyl citrate, 1,2,6-trimethyl citrate, and 1,3,5-trimethyl citrate. Methyl citrate is generally recognized as safe (GRAS) by the FDA and is approved for use in various food products, including beverages, confections, and dairy products.
The CAS Registry Mumber 5485-76-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,8 and 5 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 5485-76: (6*5)+(5*4)+(4*8)+(3*5)+(2*7)+(1*6)=117 117 % 10 = 7 So 5485-76-7 is a valid CAS Registry Number.
