Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2,5-Dihydro-1H-pyrrol-2-yl)methanol.
CATO supplies (2,5-Dihydro-1H-pyrrol-2-yl)methanol (CAS 1256643-00-1), a certified reference material (molecular formula C5H9NO, MW 99.13 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, (2,5-Dihydro-1H-pyrrol-2-yl)methanol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 99.13 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.
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), (2,5-Dihydro-1H-pyrrol-2-yl)methanol 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.
