215178-38-4 3-hydroxy-1-pyrrolidinecarboxylic acid 9H-fluoren-9-ylmethyl ester 9H-fluoren-9-ylmethyl 3-oxidanylpyrrolidine-1-carboxylate A815439 CAS 215178-38-4 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 215178-38-4 3-hydroxy-1-pyrrolidinecarboxylic acid 9H-fluoren-9-ylmethyl ester 9H-fluoren-9-ylmethyl 3-oxidanylpyrrolidine-1-carboxylate A815439.

215178-38-4 3-hydroxy-1-pyrrolidinecarboxylic acid 9H-fluoren-9-ylmethyl ester 9H-fluoren-9-ylmethyl 3-oxidanylpyrrolidine-1-carboxylate A815439 (CAS 215178-38-4) is a high-purity analytical reference standard with the molecular formula C19H31NO3 and a molecular weight of 321.45 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 215178-38-4 3-hydroxy-1-pyrrolidinecarboxylic acid 9H-fluoren-9-ylmethyl ester 9H-fluoren-9-ylmethyl 3-oxidanylpyrrolidine-1-carboxylate A815439 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 321.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
