Cat. No.: HY-101530BR
CAS No.: 9004-99-3
Synonyms: PEG 40 stearate (Standard)
Research Areas:  

Others

Polyoxyl 40 stearate (Standard) is the analytical standard of Polyoxyl 40 stearate (HY-101530B). This product is intended for research and analytical applications. Polyoxyl 40 stearate can be used as an excipient. Pharmaceutical excipients, or pharmaceutical auxiliaries, refer to other chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs .

Cat. No.: HY-184605
Metal nanoclusters, containing anywhere from a few to hundreds of atoms, bridge the gap between nanoparticles and molecular compounds, typically exhibiting molecular-like electrical and optical properties. Furthermore, metal nanoclusters possess advantages such as significant Stokes scattering and size- and ligand-dependent fluorescence characteristics, making them an emerging class of materials for constructing fluorescence platforms. Current research primarily focuses on the synthesis and application of noble metal nanoclusters like gold and silver. However, copper, belonging to the same group as gold and silver in the periodic table, is inexpensive, environmentally friendly, readily available, has a simple preparation process, and low toxicity, making it widely applicable in industry. In addition, copper nanoclusters exhibit better photostability than organic dyes and better environmental friendliness than semiconductor quantum dots, making them suitable for trace detection.

Cat. No.: HY-184617
Due to their unique physical and chemical properties, noble metal nanoparticles, represented by platinum, gold, silver, and palladium, have been extensively studied by many scientists. Palladium is a noble metal belonging to the platinum group elements. Its elemental form is a silvery-white transition metal, soft in texture and possessing good ductility and malleability. Palladium nanoparticles, due to their unique physical, chemical, and electronic properties, have shown remarkable application potential in multiple fields. The preparation methods for palladium nanoparticles mainly include chemical reduction and physical reduction methods. Chemical reduction generally involves adding a reducing agent to reduce palladium ions to elemental palladium. Common reducing agents used include sodium citrate, sodium borohydride, and hydrogen gas. Because the chemical reduction process is relatively fast, protective agents such as polyvinylpyrrolidone (PVP) are generally added to prevent palladium particles from agglomerating.

Cat. No.: HY-145149S
Duostatin 5- 13C,d3 is the 13C-labeled Duostatin 5 (HY-145149). Duostatin 5 is a ADC Cytotoxin designed based on MMAF (HY-15579) and can be used to synthesize ADCs. The preparation of Duostatin 5 has the advantages of fewer synthetic steps, simple operation, less difficulty in quality control, and more stable chemical synthesis process. Duostatin 5 can be linked to the antibody targeting 5T4 (ZV05) by cross-linking with interchain cysteines through a disubstituted C-Lock linker. Duostatin 5 is a click chemistry reagent. It contains an azide group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing alkyne groups. It can also undergo ring strain-driven alkyne-azide cycloaddition (SPAAC) with molecules containing DBCO or BCN groups[1][2].
