STERLING CE PHOSPHORAMIDITES

Glen Research CE (ß-cyanoethyl) Phosphoramidites are produced and packaged to ensure the highest performance on DNA synthesizers. Every Glen Research product is accompanied by a Certificate of Analysis and HPLC trace, showing the results of our QC testing. Every Glen Research monomer vial is specially cleaned to eliminate particulate contamination.

QUALITY ASSURANCE

Every batch of these CE Phosphoramidites is tested as follows

HPLC
a) Identity is confirmed by comparison with a reference sample.
b) Purity is determined by HPLC to be ≥98.0%.
TLC
Purity is verified by TLC.
31P NMR
Purity is determined by 31P NMR to be ≥98%.
Coupling Test
Coupling efficiency is determined to be ≥99%.
Solution Test
A 0.1M solution is determined to be clear and free of particulate contamination.
Loss on Drying
Volatile contaminants are determined to be ≤2%.

STERLING SOLVENTS/REAGENTS

All solvents and reagents are prepared to our exacting specifications to ensure the highest synthesis efficiency and are passed through a 0.2 micron filter during packaging to eliminate particulate contamination. Crystalline tetrazole solutions have been discontinued.
