Chemical Structure
Description
(S)-1-(tert-Butoxycarbonyl)-2-(3-methylbenzyl)pyrrolidine-2-carboxylic acid (CAS 1217604-87-9) is a high-purity analytical reference standard with the molecular formula C18H25NO4 and a molecular weight of 319.40 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (S)-1-(tert-Butoxycarbonyl)-2-(3-methylbenzyl)pyrrolidine-2-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures (S)-1-(tert-Butoxycarbonyl)-2-(3-methylbenzyl)pyrrolidine-2-carboxylic acid 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.
