Organic reference standards, cyclazadone (NMIA D914), Certified Reference Material (CRM)
Supplier: LGC Standards PROMOCHEM
The purity value obtained from a combination of traditional analytical techniques is 99,6 ± 1,4% mass fraction, (95% coverage interval). The purity estimate by traditional analytical techniques was obtained by subtraction from 100% of total impurities by GC-FID, thermogravimetric analysis, Karl Fischer analysis and 1H NMR and also supported by elemental microanalysis.
