Chemical Properties
White to pale brown solid
General Description
An excellent derivative for the synthesis of branched peptides and peptides modified at the lysine side-chain [1], and for the construction of templates and multifunctionalized resins for combinatorial synthesis.The side-chain Mmt group can be selectively removed in the same manner as Mtt with 1% TFA in DCM [2, 3, 4] or DCM/HFIP/TFE/TES (6.5:2:1:0.5) [5]. Alternatively, it can be removed under milder conditions with AcOH/TFE/DCM (1:2:7) [1], leaving Mtt intact.The product number for this product was previously 04-12-1232.To obtain a certificate of analysis (CoA) of a lot that begins with the letter “A”, please select the option in the right hand menu “Request a COA for Lot#s starting with A”.
Check Digit Verification of cas no
The CAS Registry Mumber 159857-60-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,8,5 and 7 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 159857-60:
(8*1)+(7*5)+(6*9)+(5*8)+(4*5)+(3*7)+(2*6)+(1*0)=190
190 % 10 = 0
So 159857-60-0 is a valid CAS Registry Number.
