Chemical Structure
Description
The occurrence of Indomethacin heptyl ester, >98% is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Indomethacin heptyl ester, >98% (CAS 282728-47-6) is a high-purity analytical reference standard with the molecular formula C26H30ClNO4 and a molecular weight of 455.97 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Indomethacin heptyl ester, >98% is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 455.97 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Indomethacin heptyl ester, >98% 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.
