Chemical Structure
Description
CATO supplies 1-(Prop-2-ynoyl)-2,3-dihydro-1h-indole-5-carboxylic acid (CAS 1152562-41-8), a certified reference material (molecular formula C12H9NO3, MW 215.20 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-(Prop-2-ynoyl)-2,3-dihydro-1h-indole-5-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 1-(Prop-2-ynoyl)-2,3-dihydro-1h-indole-5-carboxylic 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.
