1'-(tert-Butoxycarbonyl)-8-methoxyspiro[chroman-4,3'-pyrrolidine]-4'-carboxylic acid CAS 1956385-64-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1'-(tert-Butoxycarbonyl)-8-methoxyspiro[chroman-4,3'-pyrrolidine]-4'-carboxylic acid.

1'-(tert-Butoxycarbonyl)-8-methoxyspiro[chroman-4,3'-pyrrolidine]-4'-carboxylic acid (CAS 1956385-64-0) is a high-purity analytical reference standard with the molecular formula C19H25NO6 and a molecular weight of 363.40 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 1'-(tert-Butoxycarbonyl)-8-methoxyspiro[chroman-4,3'-pyrrolidine]-4'-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 363.40 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
