Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2-Dihydro Prednicarbate.
CATO supplies 1,2-Dihydro Prednicarbate (CAS 671225-26-6), a certified reference material (molecular formula C27H38O8, MW 490.59 g/mol) for analytical method development and quality control.
1,2-Dihydro Prednicarbate (C27H38O8) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
