Description
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
Benzoic acid may be used as a reference standard in determining the concentration of benzoic acid in food and milk samples using high performance liquid chromatography coupled with photodiode array detector (HPLC).[1][2]
Analysis Note
These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP 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.

An auxiliary-assisted, copper catalyzed or promoted sulfenylation of benzoic acid derivative β-C-H bonds and benzylamine derivative γ-C-H bonds has been developed. The method employs disulfide reagents, copper(II) acetate, and DMSO solvent at 90-130 °C. Application of this methodology to the
Copper-mediated C-H/C-H biaryl coupling of benzoic acid derivatives and 1,3-azoles.

Redox-neutral formation of C-P bonds in the α-position of amines was achieved via a process that features a combination of an oxidative α-C-H bond functionalization and a reductive N-alkylation. Benzoic acid functions as an efficient catalyst in this three-component reaction
