N-Trityl-glycin-<2-chlor-ethylester>, also known as N-trityl-glycine 2-chloroethyl ester, is a chemical compound with the molecular formula C22H22ClNO3. It is a derivative of glycine, an amino acid, where the amino group is protected by a trityl group (a bulky phenylmethyl group) and the carboxylic acid group is esterified with 2-chloroethanol. N-Trityl-glycin-<2-chlor-ethylester> is often used in organic synthesis and peptide chemistry as a protected amino acid building block, particularly in the synthesis of peptides and other biomolecules. The trityl group serves to protect the amino group from unwanted reactions, while the 2-chloroethyl ester group can be used for coupling reactions in peptide synthesis. The compound is typically used in the solid form and is sensitive to light and moisture, requiring storage under controlled conditions.
The CAS Registry Mumber 4194-88-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,9 and 4 respectively; the second part has 2 digits, 8 and 8 respectively. Calculate Digit Verification of CAS Registry Number 4194-88: (6*4)+(5*1)+(4*9)+(3*4)+(2*8)+(1*8)=101 101 % 10 = 1 So 4194-88-1 is a valid CAS Registry Number.
