Chemical Structure
Description
2-chloro-4-methyl-1,3-oxazole (CAS 1060816-10-5), molecular formula C4H4ClNO and molecular weight 117.53 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-chloro-4-methyl-1,3-oxazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 117.53 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.
CATO manufactures 2-chloro-4-methyl-1,3-oxazole 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.
