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.
PESTANAL™ Carpropamid, MilliporeSigma™ Supelco™
Carpropamid is widely used for the control of rice blast caused by Pyricularia oryzae. Carpropamid acts by inhibiting scytalone dehydratase enzyme involved in fungal melanin biosynthesis in a phytopathogenic fungus.
1-Methylnicotinamide chloride, ≥97.5%, MilliporeSigma™ Supelco™
1-Methylnicotinamide (MNA) is a primary metabolite of nicotinamide produced mainly by nicotinamide N-methyltransferase (NNMT) and exhibits antithrombotic and anti-inflammatory effects.
L-Glutamic acid Pharmaceutical Secondary Standard, MilliporeSigma™ Supelco™
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.
Pullulan Standard Certified Reference Material, Certified according to DIN, For GPC, 50,000, MilliporeSigma™ Supelco™
Pullulan Standards are mostly used to obtain molecular mass distribution of cellulosic samples. It mainly consists of polymaltotriose units linked together by α-(1→6) linkages.
Neotame, ≥98.0% (HPLC), MilliporeSigma™ Supelco™
Neotame is a white colored, dipeptide methyl ester, which is found to be a highly potent and non-nutritive sweetener or flavour enhancer and hence finds applications in variety of foods. It is manufactured from aspartame and 3,3-dimethylbutyraldehyde in a one-step chemical synthesis process.
Ferulic Acid Pharmaceutical Secondary Standard, MilliporeSigma™ Supelco™
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
