93778-42-8 Usage
General Description
(Carboxymethyl)trimethylammonium nitrate, also known as CTAN, is a quaternary ammonium compound that is commonly used as a phase transfer catalyst in organic synthesis. It can be synthesized by reacting trimethylamine with chloroacetic acid, followed by neutralization with nitric acid. CTAN has a positively charged nitrogen atom and a carboxymethyl group, which gives it both hydrophobic and hydrophilic properties, making it useful in transferring organic compounds from one phase to another. It is often used in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals. CTAN is also considered to be biodegradable and environmentally friendly, as it breaks down into non-toxic components over time.
Check Digit Verification of cas no
The CAS Registry Mumber 93778-42-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,7 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 93778-42:
(7*9)+(6*3)+(5*7)+(4*7)+(3*8)+(2*4)+(1*2)=178
178 % 10 = 8
So 93778-42-8 is a valid CAS Registry Number.

A dramatic effect of the ionic liquid structure in esterification reactions in protic ionic media
Chiappe, Cinzia,Rajamani, Sunita,D'Andrea, Felicia
, p. 137 - 143 (2013/02/25)
Bronsted acidic ionic liquids (ILs) have been synthesized and investigated as catalysts in esterification and transesterification reactions: simple and non-corrosive salts characterized by aliphatic cations associated with an "acidic" anion (in particular, [HSO4]-) gave the higher yields. A quite good correlation between IL acidity (H 0) and catalytic ability was found although also the hydrophilic nature of the ionic medium probably affects the process efficiency.
