Chemical Structure
Description
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 supplies Hexanedioic acid, polymer with 1,3-butanediol, 1,3-isobenzofurandione and 1,2-propanediol, octadecanoate (CAS 68238-78-8), a certified reference material (molecular formula C18H36O2C8H4O3C6H10O4C4H10O2C3H8O2, MW 744.96 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Hexanedioic acid, polymer with 1,3-butanediol, 1,3-isobenzofurandione and 1,2-propanediol, octadecanoate is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 744.96 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).
As a certified reference material (CRM), Hexanedioic acid, polymer with 1,3-butanediol, 1,3-isobenzofurandione and 1,2-propanediol, octadecanoate 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.
