General description

Ethyl 4-(dimethylamino)benzoate can have the tendency to generate free radicals on illumination and hence it can find applications as an industrial photoinitiator for polymerization.
This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034. This CRM is traceable to primary material from an NMI, e.g. NIST or NMIJ.
Certified content by quantitative NMR incl. uncertainty and expiry date are given on the certificate.
