Chemical Structure

(1R,4R)-rel-4-Amino-2-cyclopentene-1-carboxylic Acid Methyl Ester Hydrochloride CAS 77745-26-7 chemical structure

Description

The occurrence of (1R,4R)-rel-4-Amino-2-cyclopentene-1-carboxylic Acid Methyl Ester Hydrochloride is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(1R,4R)-rel-4-Amino-2-cyclopentene-1-carboxylic Acid Methyl Ester Hydrochloride (CAS 77745-26-7), molecular formula C7H11NO2HCl and molecular weight 177.63 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, (1R,4R)-rel-4-Amino-2-cyclopentene-1-carboxylic Acid Methyl Ester Hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
