In response to the market trend, the New York-based chemical supplier Alfa Chemistry announces to further optimize its offering of protection reagents by classifying them into a number of smaller groups.

After the implementation of this move, visitors to the website of Alfa Chemistry can easily locate the reagents they need by just searching or scanning through different groups, which are: 2-(trimethylsilyl)ethoxycarbonylation (Teoc) reagents, 9-fluorenylmethyloxycarbonylation (Fmoc) reagents, acetalization reagents, acylation reagents, alkoxymethylation reagents, allylation reagents, allyloxycarbonylation (Alloc) reagents, benzylation (Bn) reagents, benzyloxycarbonylation (Cbz) reagents, photolabile protection reagents, silylation reagents, sulfonylation reagents, tert-Butoxycarbonylation (Boc) reagents, thioacetalization reagents, trichloroethoxycarbonylation reagents, tritylation (Tr) reagents as well as other protecting reagents.

Organic synthesis is a preferred method to synthesize new products that do not exist in nature and to endow them with excellent properties. However, the existence of more than one functional group in the same molecule may cause unwanted reactions, which may degrade or otherwise modify the structure in an undesired way.

To avoid possible side reactions, protecting groups are used to temporarily mask the characteristic chemistry of a functional group, and the reagents that can provide the protecting groups are called protection reagents. A good protecting group should be easy to put on and remove, and be inert to the conditions of the reaction required.

“Frequently, the corresponding functional groups can be selectively protected and then reduced after the end of the reaction. Via this way, the target product can be synthesized in the targeted manner,” says the Marketing Chief of Alfa Chemistry.

A large number of protection reagents are now readily available at Alfa Chemistry, making carbohydrate, peptide and oligonucleotide synthesis reactions more easily handled in a desirable way. Below are just some of them:

1-[2-(Trimethylsilyl)ethoxycarbonyloxy]pyrrolidin-2,5-dione (CAS 78269-85-9), 4-Nitrophenyl 2-(trimethylsilyl)ethyl carbonate (CAS 80149-80-0), Fmoc chloride (CAS 28920-43-6), 9-Fluorenylmethyl carbazate (CAS 35661-51-9), Benzaldehyde dimethyl acetal (CAS 1125-88-8), 2-Methoxypropene (CAS 116-11-0), tert-Butyl[4-(dimethoxymethyl)phenoxy]dimethylsilane (CAS 118736-04-2), p-Anisaldehyde (CAS 123-11-5), 2,2-Dimethyl-1,3-propanediol (CAS 126-30-7), 1,3-Bis(trimethylsilyloxy)propane (CAS 17887-80-8), 6-bromo-7-hydroxy-4-(hydroxymethyl)-2H-chromen-2-one (CAS 223420-41-5),rac-1-(2-Nitrophenyl)ethanol (CAS 3205-25-2), 4',5'-Dimethoxy-2'-nitroacetophenone (CAS 4101-32-0), etc.

“All chemicals provided by Alfa Chemistry are strictly QC assessed so that high quality is guaranteed. Technical documents such as COA are also provided,” the Marketing Chief further explains.
