Applications
Isotope labeling studies
Organic synthesis research
Protective group
Tert-butoxycarbonyl (Boc) group temporarily masks reactive functional groups during synthesis
Cleavage
Boc group can be removed using trifluoroacetic acid (TFA) or hydrochloric acid (HCl) to reveal the free amino group
Synthesis
Prepared through the reaction of the corresponding amino acid with di-tert-butyl dicarbonate (Boc2O) or other Boc-protecting agents
Reactivity
Reacts with various reagents to form different derivatives, depending on the specific synthetic route
Safety precautions
Handle with care, use appropriate personal protective equipment (PPE), and follow proper disposal procedures for waste materials
Storage
Store in a cool, dry place, away from light and heat, and in a sealed container to prevent degradation or contamination
Check Digit Verification of cas no
The CAS Registry Mumber 145142-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,1,4 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 145142-99:
(8*1)+(7*4)+(6*5)+(5*1)+(4*4)+(3*2)+(2*9)+(1*9)=120
120 % 10 = 0
So 145142-99-0 is a valid CAS Registry Number.
