产品说明

一般描述

Dioxybenzone belongs to the class of organic UV filters, which find wide application in personal care products and food packaging materials. These filters are prevalently employed as active ingredients in sunscreen formulations due to their ability to emit and/or absorb UVA and UVB radiations. Owing to their ubiquitous use and discharge into the environment, they are identified as common environmental pollutants.

应用

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Dioxybenzone may be used as an analytical standard for the determination of the analyte in animal samples, artificial seawater samples, fresh and saline waters by various chromatographic techniques.

包装

Bottomless glass bottle. Contents are inside inserted fused cone.

其他说明

Ion Mobility: TWCCSN2 value of 149.3 Å2 [M+H]+, 166.1 Å2 [M+Na]+ and 151.1 Å2 [M-H]-

The collision cross section (CCS) measurement was provided by Waters Corporation, using the SYNAPT XS mass spectrometer.
For a description and overview of how ion mobility enables the measurement of the CCS of an ion visit ims.waters.com.
Further information on the SYNAPT XS mass spectrometer can be found on the IMS microsite and product webpage.

TWCCS measurements are expected to be within 2% of this reference value.
