Chemical Structure

3-Pyrrolidinone CAS 96-42-4 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 3-Pyrrolidinone.

CATO supplies 3-Pyrrolidinone (CAS 96-42-4), a certified reference material (molecular formula C4H7NO, MW 85.10 g/mol) for analytical method development and quality control.

Owing to an amide group, a hydroxyl group, an ether linkage, 3-Pyrrolidinone is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 85.10 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.

CATO manufactures 3-Pyrrolidinone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
