Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Pyridine, 2,2′-[(4S,5S)-2,2-dimethyl-1,3-dioxolane-4,5-diyl]bis[6-[(4R)-4,5-dihydro-4-(1-methylethyl)-2-oxazolyl]-.
Pyridine, 2,2′-[(4S,5S)-2,2-dimethyl-1,3-dioxolane-4,5-diyl]bis[6-[(4R)-4,5-dihydro-4-(1-methylethyl)-2-oxazolyl]- (CAS 197918-39-1), molecular formula C27H34N4O4 and molecular weight 478.58 g/mol, is a CATO reference standard with documented purity and traceability.
Pyridine, 2,2′-[(4S,5S)-2,2-dimethyl-1,3-dioxolane-4,5-diyl]bis[6-[(4R)-4,5-dihydro-4-(1-methylethyl)-2-oxazolyl]- (C27H34N4O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Pyridine, 2,2′-[(4S,5S)-2,2-dimethyl-1,3-dioxolane-4,5-diyl]bis[6-[(4R)-4,5-dihydro-4-(1-methylethyl)-2-oxazolyl]- meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
