Acids and Esters

Acids and esters that meet certain requirements can be used as certified reference materials and they can be widely used in chromatographic analysis to calibrate instruments, evaluate test methods, achieve quantitative and qualitative analysis. Acids and esters certified reference materials are generally of high purity and have one or more characteristic values. In addition, acids and esters certified reference materials are accompanied by certificates, which makes them traceable. Furthermore, acids and esters certified reference materials can be in liquid or solid state to meet different use and transportation requirements. Commonly used acids and esters certified reference materials include syringic acid, anemonin, salicylic acid, cinnamyl acetate, benzyl acetate, 4-hydroxybenzoic acid, primeverin and others.

Application fields

Food and beverage field: The high content of acids and esters in food and beverage will affect the safety and cause harm to human health. Therefore, it is of great importance to use acids and esters certified reference materials to realize qualitative or quantitative detection of acids and esters. For example, the content of syringic acid in needle mushroom can be determined by reversed-phase high performance liquid chromatography using syringic acid certified reference material. In addition, it has been reported that high performance liquid chromatography can be used for the rapid detection of methyl syringic acid in honey, in which the methyl syringic acid certified reference material is necessary.
Cosmetics and fragrances field: Acids and esters are very common in the field of cosmetics and fragrances and in order to ensure their quality, it is necessary to achieve quantitative and qualitative analysis of acids and esters in virtue of acids and esters certified reference materials. For example, the content of salicylic acid in cosmetics can be measured by high performance liquid chromatography. In this method, the salicylic acid certified reference material is used to establish a standard curve. According to the peak position and peak strength of the standard curve, the content of salicylic acid in the sample can be determined. Furthermore, this method has the advantages of high sensitivity, good selectivity and simplicity.
