Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 82787-69-7 5-Methyl-benzo[b]thiophene-2-carboxylic acid methyl ester MFCD11044569.
82787-69-7 5-Methyl-benzo[b]thiophene-2-carboxylic acid methyl ester MFCD11044569 (CAS 82787-69-7), molecular formula C11H10O2S and molecular weight 206.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 82787-69-7 5-Methyl-benzo[b]thiophene-2-carboxylic acid methyl ester MFCD11044569 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.26 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.
CATO manufactures 82787-69-7 5-Methyl-benzo[b]thiophene-2-carboxylic acid methyl ester MFCD11044569 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.
