Chemical Structure
Description
The occurrence of tert-Butyl 1-(2-chloroethyl)cyclobutane-1-carboxylate is closely related to 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.
CATO supplies tert-Butyl 1-(2-chloroethyl)cyclobutane-1-carboxylate (CAS 2137598-25-3), a certified reference material (molecular formula C11H19ClO2, MW 218.72 g/mol) for analytical method development and quality control.
Structurally, tert-Butyl 1-(2-chloroethyl)cyclobutane-1-carboxylate (C11H19ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 218.72 g/mol, it falls into the medium-molecular-weight range. 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 1-(2-chloroethyl)cyclobutane-1-carboxylate 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.
