Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 227.69 g/mol gives Isobutyl (4-chlorophenyl)carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Isobutyl (4-chlorophenyl)carbamate (CAS 25217-24-7), molecular formula C11H14ClNO2 and molecular weight 227.69 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Isobutyl (4-chlorophenyl)carbamate (C11H14ClNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 227.69 g/mol, it falls into the medium-molecular-weight range. 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.
CATO manufactures Isobutyl (4-chlorophenyl)carbamate 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.
