General description: | Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Ethyl maltol is a complex heterocyclic organic compound widely used as a flavor enhancer in wine. It helps to prevent haze and to stabilize the taste of wine. Ethyl maltol can inhibit the growth of fungi and also acts as a smoothing/stabilizing agent in wines. |
Other Notes: | This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis. |
