Medchemexpress LLC 4-pentynoic acid | 6089-09-4 | MFCD00004407 | 98.4% | 98.10 | C5H6O2 | 10g
4-Pentynoic acid (Propargylacetic acid) is an intermediate to produce biologically active compounds 4-Pentynoic acid is widely utilized as a building block for the synthesis of eight sequence-defined model oligomers[1] 4-Pentynoic acid is a click chemistry reagent it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups
Medchemexpress LLC Pentynoic acid STP ester sodium | 1807530-14-8 | 99.5% | C11H5F4NaO5S | 10MG
Pentynoic acid STP ester sodium is a water-soluble, alkyne-activated STP (sulfotetrafluorophenyl) ester reagent used to introduce a terminal alkyne handle onto proteins and peptides for bioconjugation. It enables amine-targeted coupling under mild, aqueous conditions and subsequent alkyne-based conjugation such as copper(I)-catalyzed azide-alkyne cycloaddition.
- Contains a terminal propargyl (alkyne) group for click chemistry.
- STP activated ester enables efficient coupling to lysine residues.
- Water-soluble formulation suitable for reactions in aqueous buffers.
- High purity for reproducible bioconjugation outcomes.
- DMSO-soluble at high concentration; ultrasonication may be required.
- Store sealed and away from moisture to preserve reagent activity.
Medchemexpress LLC E -Crotonic acid | 107-93-7 | 100g
NSC 8751 (trans-2-Butenoic acid trans-Crotonic acid) is an unsaturated carboxylic acid compound containing -unsaturated carboxylic acid groups NSC 8751 is one of the important analogs for evaluating the safety of fragrance ingredients and is used to evaluate the toxicological properties of compounds with similar structures When NSC 8751 is applied to local lymph nodes a 50% concentration does not cause skin sensitization Structural analogs of NSC 8751 have been shown to be non-genotoxic trans-Crotonic acid can be used in the preparation of cosmetics and food additives[1][2]
