Propargyl-PEG5-Ms represents a bifunctional linker possessing a proparygyl group reactive towards azides in copper (I) click chemistry to form stable triazoles with the target compound as well as a mesyl group which is a good leaving group for nucleophilic reactions.

OG 488 alkyne is a bright, green-fluorescent alkyne-activated probe routinely used for imaging of azide-containing biomolecules. OG 488 Alkyne reacts with azides via a copper-catalyzed click reaction (CuAAC) to form a stable triazole linker.

ROX alkyne, 6-isomer is an alkyne derivative of the bright red-emitting dye ROX (Rhodamine X, Rhodamine 101). Due to its quantum yield approaching unity, ROX is a popular dye for qPCR and microscopy applications. It is used for fluorescent labeling of azide-containing biomolecules via copper-catalyzed click reaction.

Hex-5-ynehydrazide is a bifunctional linker reagent with a terminal hydrazide group and a propargyl group. The hydrazide group can react with an aldehyde to form a semi-permanent hydrozone bond. The propargyl group can be linked to azide-containing biomolecules via Click Chemistry.

BP Fluor 430 Alkyne is a green-fluorescent alkyne-activated probe routinely used for imaging of moderate to high abundance azide-containing biomolecules. BP Fluor 430 Alkyne reacts with azides via a copper-catalyzed click reaction (CuAAC) to form a stable triazole linker. BP Fluor 430 is a bright, photostable, green-fluorescent probe optimally excited near 430 nm. This probe is water-soluble and its fluorescence is pH independent over a wide pH range.

BP Fluor 405 alkyne triTEA is a blue-fluorescent dye that often used in multi-color applications, including flow cytometry and super-resolution microscopy using STORM. Its excitation is ideally suited for the 407 nm spectral line of the krypton laser or the 408 nm violet laser diode. BP Fluor 405 alkyne triTEA reacts with azides via a copper-catalyzed click reaction (CuAAC) to form a stable triazole linker. A probe for copper-less detection (BP Fluor 405 DBCO) is also available for application where the presence of copper is not acceptable.

Thalidomide-NH-C2-alkyne contains an E3 ligase ligand with an alkyl linker, and a terminal alkyne. Thalidomide-NH-C2-alkyne is ready for conjugation to target proteins for PROTAC R&D.

OSI-413 (free base) (CP 373413) is a major metabolite of Erlotinib (HY-50896). Erlotinib (CP-358774) is a directly acting EGFR tyrosine kinase inhibitor, with an IC₅₀ of 2 nM for human EGFR.

RNA recruiter-linker 1 is the RNA ligand-linker part of RNAse L RIBOTAC (HY-168455), an RNA-degrading chimera which binds to a four-way RNA helix called SL5 in the 5’ UTR of the SARS-CoV-2 RNA genome and inhibits the virus replication in lung epithelial carcinoma cells. RNA recruiter-linker 1 can be utilized in the synthesis of RIBOTAC.

F-ara-EdU is a low-toxic, highly stable probe for DNA synthesis that is used as a marker for cell proliferation and DNA replication by binding to DNA or RNA in cells. F-ara-EdU can also be used to detect the rate of DNA synthesis within cells, as well as to study the mechanisms of DNA repair and damage.
