Troc-L-Thr-ODpm, also known as (2S,3S)-2-[(tert-butoxycarbonyl)amino]-3-[(9H-fluoren-9-ylmethoxy)carbonyl]-1,4-thiazolidine-4-carboxylic acid, is a synthetic peptide building block used in the solid-phase synthesis of peptides and proteins. It features a L-threonine residue with a Troc (2,2,2-trichloroethoxycarbonyl) protecting group on the amino group and an ODpm (9H-fluoren-9-ylmethoxycarbonyl) protecting group on the carboxylic acid group. These protecting groups are crucial for preventing unwanted side reactions during peptide synthesis and are removed at specific stages of the process to allow for further elongation of the peptide chain. Troc-L-Thr-ODpm is a valuable component in the repertoire of chemists working on peptide synthesis, enabling the creation of complex peptide structures with precise control over the sequence and protection of functional groups.
The CAS Registry Mumber 98694-92-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,9 and 4 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 98694-92: (7*9)+(6*8)+(5*6)+(4*9)+(3*4)+(2*9)+(1*2)=209 209 % 10 = 9 So 98694-92-9 is a valid CAS Registry Number.
