Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Carbonic acid, polymer with 2,6-bis[(2-hydroxy-5-methylphenyl)methyl]-4-methylphenol and 4,4'-(1-methylethylidene)bis[phenol].
CATO supplies Carbonic acid, polymer with 2,6-bis[(2-hydroxy-5-methylphenyl)methyl]-4-methylphenol and 4,4'-(1-methylethylidene)bis[phenol] (CAS 68958-04-3), a certified reference material (molecular formula C23H24O3C15H16O2CH2O3, MW 638.76 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Carbonic acid, polymer with 2,6-bis[(2-hydroxy-5-methylphenyl)methyl]-4-methylphenol and 4,4'-(1-methylethylidene)bis[phenol] is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 638.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Carbonic acid, polymer with 2,6-bis[(2-hydroxy-5-methylphenyl)methyl]-4-methylphenol and 4,4'-(1-methylethylidene)bis[phenol] 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.
