Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2E)-3-{3-[(4-Chloro-1H-pyrazol-1-yl)methyl]-4-methoxyphenyl}acrylic acid (CAS 1020050-91-2), molecular formula C14H13ClN2O3 and molecular weight 292.72 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2E)-3-{3-[(4-Chloro-1H-pyrazol-1-yl)methyl]-4-methoxyphenyl}acrylic acid (C14H13ClN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures (2E)-3-{3-[(4-Chloro-1H-pyrazol-1-yl)methyl]-4-methoxyphenyl}acrylic acid 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.
