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 1-Methylindoline-5-carboxylic acid.
1-Methylindoline-5-carboxylic acid (CAS 380922-37-2), molecular formula C10H11NO2 and molecular weight 177.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-Methylindoline-5-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.20 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.
CATO manufactures 1-Methylindoline-5-carboxylic 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.
