3949-47-1 Usage
General Description
Hexabutylthiophosphoramide, also known as HBT, is an organophosphorus compound used as a reagent in organic synthesis. It is a clear, colorless liquid with a strong odor, and is commonly used as a phosphitylating agent in organic chemistry reactions. HBT is utilized in the synthesis of phosphoramidite building blocks for oligonucleotide synthesis, and is also used in the preparation of phosphoramidite reagents for automated DNA and RNA synthesis. Additionally, HBT is used as a coupling reagent in the production of peptide and protein conjugates. Due to its reactivity and high potential for reaction with moisture, HBT must be handled and stored carefully.
Check Digit Verification of cas no
The CAS Registry Mumber 3949-47-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,4 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3949-47:
(6*3)+(5*9)+(4*4)+(3*9)+(2*4)+(1*7)=121
121 % 10 = 1
So 3949-47-1 is a valid CAS Registry Number.
