Application


  • Exploring the binding affinity and characteristics of DcitOBP9 in citrus psyllids.: This study delves into the interactions between DcitOBP9, a key odorant-binding protein, and citral in citrus psyllids, providing insights into pest behavior and potential targets for eco-friendly pest management strategies (Pei et al., 2024).

  • Synergistic anti-virulence efficacy of citral and carvacrol against mixed vaginitis causing Candida albicans and Gardnerella vaginalis: An in vitro and in vivo study.: Demonstrates the combined use of citral and carvacrol as a potent anti-virulence strategy against pathogens in mixed vaginitis, showcasing a promising lead for non-antibiotic treatments (Jothi and Gowrishankar, 2024).

  • Effect of polyethoxylated flavonoids (PMFs)-loaded citral and chitosan composite coatings on citrus preservation: From the perspective of fruit resistance.: Discusses innovative food preservation techniques using citral-infused coatings to enhance the storage life and quality of citrus fruits, addressing critical issues in food technology (Li et al., 2024).

  • Synthesis, antifungal activity and action mechanism of novel citral amide derivatives against Rhizoctonia solani.: Explores the synthesis of citral derivatives for use as antifungal agents, offering new solutions for controlling fungal diseases in crops with potential applications in sustainable agriculture (Zhang et al., 2024).

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. What is the apparent molarity of Citral, Products W230316, C83007, and W230308?

    The apparent molarity of a neat liquid may be calculated from the density and molecular weight.  In the case of citral, the density is 0.888 g/mL and the molecular weight is 152.23 g/mole. By writing the density as 888 g/L, the calculation is 888 g/L divided by 152.23 g/mole = 5.83 mole/L, or 5.83 M.
