Additional Infomation Ascr#3 is an (omega-1)-hydroxy fatty acid ascaroside obtained by formal condensation of the alcoholic hydroxy group of (2E,8R)-8-hydroxynon-2-enoic acid with ascarylopyranose (the alpha anomer). It is a major component of the dauer pheromone, used by the nematode Caenorhabditis elegans as a population-density signal to promote entry into an alternate larval stage, the nonfeeding and highly persistent dauer diapause, and also synergises with ascr#2, ascr#4, and ascr#8 in male attraction. It has a role as a Caenorhabditis elegans metabolite and a pheromone. It is an alpha,beta-unsaturated monocarboxylic acid and an (omega-1)-hydroxy fatty acid ascaroside. It is functionally related to a (2E,8R)-8-hydroxynon-2-enoic acid. It is a conjugate acid of an ascr#3(1-).
ascaroside C9 has been reported in Caenorhabditis elegans with data available.

Solubility Data


Solubility (In Vitro) DMSO : ~200 mg/mL (~661.46 mM)
Solubility (In Vivo) Solubility in Formulation 1: ≥ 5 mg/mL (16.54 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 50.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 5 mg/mL (16.54 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 50.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

Solubility in Formulation 3: ≥ 5 mg/mL (16.54 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 50.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

1 mM 3.3073 mL 16.5366 mL 33.0732 mL

10 mM 0.3307 mL 1.6537 mL 3.3073 mL
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
