2-Methyl-1,3-benzoxazole-5-carbonyl chloride CAS 444777-18-8

Description

Compared with other compounds in its class, the molecular weight of 195.60 g/mol gives 2-Methyl-1,3-benzoxazole-5-carbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Methyl-1,3-benzoxazole-5-carbonyl chloride (CAS 444777-18-8) is a high-purity analytical reference standard with the molecular formula C9H6ClNO2 and a molecular weight of 195.60 g/mol.

2-Methyl-1,3-benzoxazole-5-carbonyl chloride (C9H6ClNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
