Organic sulfuric acids and derivatives
AdipoGen DPD sulfate
Chemical. CAS 6283-63-2. Formula C10H18N2O4S. MW 262.33. N,N-Diethyl-p-phenylenediamine sulfate DPD is used as a chromogenic indicator or reagent in analytical chemistry and in water quality testing. It is commonly used in a test called the DPD method, primarily for the measurement of free and total chlorine by titrimetric, colorimetric and spectroscopic methods in water. DPD reacts with free chlorine hypochlorous acid and hypochlorite ions to form a pink or magenta-colored compound. The intensity of the color is directly proportional to the concentration of chlorine, making it a convenient method for chlorine quantification. In general, it is used for spectrophotometric determination KIO4 levels, drugs containing phenolic groups or aromatic amino groups and as a peroxidase substrate. DPD has been developed as a color developing agent in photgraphy.
AdipoGen Colistin sulfate USP Grade
Chemical. CAS 1264-72-8. Formula 2C52H98N16O13 . 5H2SO4 unspec.. MW 2801.7. Isolated from Bacillus polymyxa. Very potent polymyxin antibiotic. Has only one amino acid difference compared to polymyxin B. Antimicrobial. Targets the lipopolysaccharide LPS of the outer membrane of Gram-negative bacteria. Competitively displaces divalent cations Ca2 and Mg2 from the negatively-charged phosphate groups LPS, causing disruption of the membrane. This increases the permeability of the cell envelope, leakage of cell contents, leading to apoptosis and cell death. Used against multidrug-resistant Gram-negative bacterial infections.
Medchemexpress LLC Chondroitin sulfate methacryloyl | 99.5% | 10 MG
Chondroitin sulfate methacryloyl (CSMA) is a methacrylated derivative of chondroitin sulfate developed for photocrosslinkable hydrogel formation and 3D bioprinting. It is biocompatible, forms fibrous hydrogels under photoinitiation, and the degree of methacrylation enables tuning of mechanical strength, swelling behavior, and enzymatic degradability. Supplied as a white to off-white powder; soluble in water (≈20 mg/mL with sonication). Store powder at -20 °C.
- Biocompatible methacrylated polysaccharide suitable for hydrogel scaffolds.
- Photocrosslinkable for rapid curing with appropriate photoinitiators.
- Degree of methacrylation tunable to adjust mechanics and degradation.
- Soluble in water with sonication for solution preparation.
- Stable as a powder at -20 °C for long-term storage.

AdipoGen Vinblastine sulfate salt
Chemical. CAS 143-67-9. Formula C46H58N4O9 . H2SO4. MW 909.05. Vinblastine sulfate is a vinca alkaloid and a chemical analog of vincristine. It is an anticancer agent with anti-mitotic properties and immunosuppressive activity. Vinblastine sulfate depolymerizes microtubules by binding tubulin and inducing self-association in spiral aggregates. This reaction that appears to be regulated by the C-terminus of beta-tubulin and is enhanced by GDP and GTP. Vinblastine sulfate has been observed to arrest the cell cycle in the G2/M-phase by blocking mitotic spindle formation. Vinblastine sulfate has also been documented to trigger Raf-1 activation and phosphorylation of Bcl-2 family proteins, to induce p53 expression, and to induce apoptosis in several tumor cell lines. Shown to inhibit autophagosome maturation.

Sigma Aldrich Fine Chemicals Biosciences Polymyxin B sulfate salt p
Polymyxin B is a member of the polymyxin group of antibiotics obtained from different strains of Bacillus polymyxa and related species. It contains a cyclic heptapeptide unit and a tripeptide side chain which is N-acylated by a fatty acyl residue. Polymyxin B sulfate salt is generally used for the treatment of Gram-negative bacterial infections.Chemical structure peptide
