Chemical formula Synonyms CAS number C 10 H 16 N 2 O 8: Ethylenediaminetetraacetic acid (EDTA): 6381–92–6 C 12 H 22 O 11: sucrose: 57–50–1 C 18 H 29 O 3 S: sodium dodecyl benzenesulfonate: 2155–30–0
[9] [10] Its chemical formula is CH 3 (CH 2) 14 COOH, and its C:D ratio (the total number of carbon atoms to the number of carbon-carbon double bonds) is 16:0. It is a major component of palm oil from the fruit of Elaeis guineensis ( oil palms ), making up to 44% of total fats.
The check digit is found by taking the last digit times 1, the preceding digit times 2, the preceding digit times 3 etc., adding all these up and computing the sum modulo 10. For example, the CAS number of water is 7732-18-5: the checksum 5 is calculated as (8×1 + 1×2 + 2×3 + 3×4 + 7×5 + 7×6) = 105; 105 mod 10 = 5.
β-Propiolactone, often simply called propiolactone, is an organic compound with the formula CH 2 CH 2 CO 2.It is a lactone family, with a four-membered ring. It is a colorless liquid with a slightly sweet odor, highly soluble in water and organic solvents.
For this reason it is commonly used in fragrances and artificial flavors. [3] The compound was named heliotropin after the 'cherry pie' notes found in the heliotrope flower's fragrance (even though the chemical is not present in the flower's true aroma). [10] Perfumers began to use the fragrance for the first time by the early 1880s. [11]
1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC, EDAC or EDCI) is a water-soluble carbodiimide usually handled as the hydrochloride. [1] It is typically employed in the 4.0-6.0 pH range. It is generally used as a carboxyl activating agent for the coupling of primary amines to yield amide bonds.
