Chemical Structure
Description
The occurrence of (E)-3-(3-((4-chloro-3,5-dimethyl-1H-pyrazol-1-yl)methyl)-4-methoxyphenyl)acrylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(E)-3-(3-((4-chloro-3,5-dimethyl-1H-pyrazol-1-yl)methyl)-4-methoxyphenyl)acrylic acid (CAS 1020050-88-7), molecular formula C16H17ClN2O3 and molecular weight 320.77 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (E)-3-(3-((4-chloro-3,5-dimethyl-1H-pyrazol-1-yl)methyl)-4-methoxyphenyl)acrylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.77 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), (E)-3-(3-((4-chloro-3,5-dimethyl-1H-pyrazol-1-yl)methyl)-4-methoxyphenyl)acrylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
