Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 4-acetamido-5-chloro-2-(prop-2-yn-1-yloxy)benzoate.
Methyl 4-acetamido-5-chloro-2-(prop-2-yn-1-yloxy)benzoate (CAS 89481-87-8) is a high-purity analytical reference standard with the molecular formula C13H12ClNO4 and a molecular weight of 281.69 g/mol.
Methyl 4-acetamido-5-chloro-2-(prop-2-yn-1-yloxy)benzoate (C13H12ClNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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.
CATO manufactures Methyl 4-acetamido-5-chloro-2-(prop-2-yn-1-yloxy)benzoate 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.
