6149-49-1 Usage
General Description
Undecanoic acid, 11-hydroxy-, ethyl ester is a chemical compound that is derived from undecanoic acid, a naturally occurring fatty acid found in some plants and animals. The ethyl ester form of undecanoic acid is a synthetic compound commonly used in the production of various personal care products, such as perfumes and cosmetics. It is also used as a flavoring agent in the food industry. Undecanoic acid, 11-hydroxy-, ethyl ester has a wide range of applications due to its pleasant odor and flavor, as well as its ability to act as a surfactant and emulsifier. However, it is important to handle this chemical with care, as it may cause irritation to the skin, eyes, and respiratory system if not properly handled and used in a well-ventilated area.
Check Digit Verification of cas no
The CAS Registry Mumber 6149-49-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,4 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6149-49:
(6*6)+(5*1)+(4*4)+(3*9)+(2*4)+(1*9)=101
101 % 10 = 1
So 6149-49-1 is a valid CAS Registry Number.

A Simple and Mild Esterification Method for Carboxylic Acids Using Mixed Carboxylic-Carbonic Anhydrides
Kim, Sunggak,Lee, Jae In,Kim, Youn Chul
, p. 560 - 565 (2007/10/02)
A simple and mild esterification method using mixed carboxylic-carbonic anhydrides has been developed.Simple aliphatic carboxylic esters are prepared in high yields by the reaction of acids with equimolar amounts of chloroformates (2,2,2-trichloroethyl chloroformate is an exception) and triethylamine in the presence of a catalytic amount of 4-(dimethylamino)pyridine.Although aromatic acids give a mixture of the ester, the acid anhydride, and the carbonate under normal conditions utilized in this study, it is found that increasing the amount of 4-(dimethylamino)pyridine drastically decreases the formation of the acid anhydride and the carbonate, affording a satisfactory yield of the ester.This method reaches a limit with sterically hindered acids and the formation of the acid anhydride and the carbonate is favored.
