Chemical Structure

Methyl (R)-(+)-2-chloropropionate CAS 77287-29-7 chemical structure

Description

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.

CATO supplies Methyl (R)-(+)-2-chloropropionate (CAS 77287-29-7), a certified reference material (molecular formula C4H7ClO2, MW 122.55 g/mol) for analytical method development and quality control.

The molecular framework of Methyl (R)-(+)-2-chloropropionate (C4H7ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
