18933-33-0 Usage
General Description
"(3-cyano-2-hydroxypropyl)trimethylammonium chloride" (also known as "CHPTAC") is an organochemical compound that exhibits cationic characteristics. This quaternary ammonium compound is used extensively in varied applications due to its chief property as a cationic etherification agent. In terms of structure, it includes a cyano group, a hydroxy group, and a trimethylammonium chloride group. CHPTAC's most prominent use is in modifying natural and synthetic polymers into cationic or amphoteric derivatives, utilized in industries like paper, textile, water treatment, personal care products and others. The chloride anion in the compound enhances its solubility in water, making it an ideal product for applications that require water solubility.
Check Digit Verification of cas no
The CAS Registry Mumber 18933-33-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,3 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18933-33:
(7*1)+(6*8)+(5*9)+(4*3)+(3*3)+(2*3)+(1*3)=130
130 % 10 = 0
So 18933-33-0 is a valid CAS Registry Number.

Paragraph 0030; 0031; 0032; 0033, (2017/08/29)
The invention provides a preparation method of levocarnitine. The preparation method comprises the following steps: taking epoxy chloropropane as a starting material, then carrying out amination, cyaniding and carrying out ester exchange under the action of lipase CALB to obtain corresponding chiral ester, then carrying out alkaline hydrolysis and acidification, and then removing chlorine ions under the action of strongly alkaline resin, so that the levocarnitine finished product is obtained. In the invention, acid resin is used in an ester exchange process, and recemization can be realized, so that yield and optical purity of the levocarnitine are improved.
