General Description


Fmoc-Cl 98% | Fmoc chloride |  9-Fluorenylmethyl chloroformate | CAS 28920-43-6

Fmoc-Cl ( Fmoc chloride) is a kind of acid chloride. Acid chloride refers to a compound containing -C(O)Cl functional group, which belongs to a class of acid halides, and is a carboxylic acid derivative formed after the hydroxyl group in the carboxylic acid is replaced by chlorine. The simplest acid chloride is formyl chloride.

Fmoc-cl is used to prepare N-protected amino acids in solid-phase peptide synthesis; it is used to synthesize bicyclic proline analogs as an amino-protecting reagent. It can also be used as an amino acid derivative reagent for HPLC and capillary electrophoresis analysis, N-protection in peptides and oligonucleotide synthesis

Fmoc-Cl is used to protect the amino groups of various nucleosides, including adenosine, cytidine, guanosine and the corresponding 2-deoxynucleosides. Fmoc protected nucleosides can be obtained in high yield. Fmoc-Cl can also be used for hydroxyl protection, such as the protection of hydroxyl groups on sugars, etc.

Omizzur Biotech supplies a wide range of amino protectors,low price in stock and global delivery.
