(S)-Ethyl 4-amino-5-(hydroxymethyl)-2-oxo-2,5-dihydro-1H-pyrrole-3-carboxylate (CAS 195525-52-1) is a high-purity analytical reference standard with the molecular formula C8H12N2O4 and a molecular weight of 200.19 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (S)-Ethyl 4-amino-5-(hydroxymethyl)-2-oxo-2,5-dihydro-1H-pyrrole-3-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), (S)-Ethyl 4-amino-5-(hydroxymethyl)-2-oxo-2,5-dihydro-1H-pyrrole-3-carboxylate 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.
