General description
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.
Application
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
Analysis Note
These secondary standards offer multi-traceability to the USP and EP (PhEur) primary standards, where they are available.
Other Notes
This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
To see an example of a Certificate of Analysis for this material enter LRAA9010 in the slot below. This is an example certificate only and may not be the lot that you receive.

Veratrylchitosan, a polysaccharide-supported lignin model compound, has been synthesised by covalently attaching 3-(3,4-dimethoxybenzyloxy)propionic acid to the polysaccharide chitosan through an amide linkage. When this polymer was used as a substrate in the oxidation promoted by lignin peroxidase (LiP), significant decomposition

The activities of carboxymethylcellulase and xylanase in the higher basidial fungus Cerrena unicolor grown in avicel-containing medium reached 1.95 and 1.50 units per mg protein, respectively, whereas in mannitol-containing medium they ranged from 0.02 to 0.05 units per mg protein.

Normal root cultures of Capsicum frutescens biotransform externally fed precursors, like caffeic acid and veratraldehyde, to vanillin and other related metabolites. The bioconversion of caffeic acid to further metabolites--viz. vanillin, vanillylamine, vanillic acid--was shown to be elicited by treating the

Laccases play an important role in the biological break down of lignin and have great potential in the deconstruction of lignocellulosic feedstocks. We examined 16 laccases, both commercially prepared and crude extracts, for their ability to oxidize veratryl alcohol in
