Description
1-Naphthalenecarboxylicacid,5-[2-(2,5-dihydro-2-oxo-1H-pyrrol-3-yl)ethyl]-3,4,4a,5,6,7,8,8a-octahydro-5,6,8a-trimethyl-,(4aR,5S,6R,8aR)- 310433-44-4 (CAS 310433-44-4) is a high-purity analytical reference standard with the molecular formula C20H29NO3 and a molecular weight of 331.45 g/mol.
1-Naphthalenecarboxylicacid,5-[2-(2,5-dihydro-2-oxo-1H-pyrrol-3-yl)ethyl]-3,4,4a,5,6,7,8,8a-octahydro-5,6,8a-trimethyl-,(4aR,5S,6R,8aR)- 310433-44-4 (C20H29NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Naphthalenecarboxylicacid,5-[2-(2,5-dihydro-2-oxo-1H-pyrrol-3-yl)ethyl]-3,4,4a,5,6,7,8,8a-octahydro-5,6,8a-trimethyl-,(4aR,5S,6R,8aR)- 310433-44-4 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.
