Chemical Structure
Description
CATO supplies tert-butyl (2R)-2-(2-chloroacetamido)-4-methylpentanoate (CAS 1909288-17-0), a certified reference material (molecular formula C12H22ClNO3, MW 263.76 g/mol) for analytical method development and quality control.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, tert-butyl (2R)-2-(2-chloroacetamido)-4-methylpentanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 263.76 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.
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 tert-butyl (2R)-2-(2-chloroacetamido)-4-methylpentanoate 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.
